Speaking at Paris Blockchain Week 2025, Back argued that rising inflation and monetary instability globally will drive wider Bitcoin adoption. He compared Bitcoin to gold, highlighting its scarcity and growing recognition as a store of value, despite its recent 30% correction from its all-time high above $109,000. "Bitcoin has the advantage of being like gold – it's a scarce asset with an adoption curve," he said. Back noted that major currencies like the US dollar and euro have seen their supply increase by more than 50% in the past five years, a trend that could propel Bitcoin as a hedge against monetary destabilization. He predicted a 10-15% inflation rate in the next decade, a return difficult to match with stocks or housing, and that Bitcoin could compete with gold and potentially absorb some of its use cases as a geopolitical hedge. He also attributed the potential for Bitcoin's increased adoption to the recent approval of US-based spot Bitcoin ETFs and a more crypto-friendly US administration under President Trump, citing the removal of regulatory hurdles like Operation Chokepoint 2.0. Back advocated for private investors to buy Bitcoin first, before governments, to avoid a competitive rush of government investment. President Trump's executive order to create a Bitcoin reserve using seized Bitcoin is seen as a significant step towards Bitcoin's integration into the traditional financial system.

On-chain data reveals that Ethereum has fallen below all major investor cost basis levels except one...On-chain data reveals that Ethereum has fallen below all major investor cost basis levels except one: the Realized Price of mega-whale holders. A CryptoQuant analysis by MAC_D highlights this price level as a potential support point. The Realized Price is an on-chain metric representing the average cost basis for a group of ETH holders. When this metric falls below the spot price, it indicates average holders are experiencing net losses. Conversely, if above the spot price, the group is collectively profitable. This metric is crucial in on-chain analysis, as holder behavior often correlates with their profit/loss status. A retest of the acquisition level from above may encourage accumulation, while a retest from below could spur selling pressure. The network-wide Realized Price, currently around $2,250 for ETH, previously provided support last year but has failed to do so recently, meaning the average Ethereum holder is now in the red. The Realized Price for individual cohorts holding 100-1,000 ETH, 1,000-10,000 ETH, 10,000-100,000 ETH, and over 100,000 ETH, show that the recent market downturn has put three cohorts underwater. Only the mega-whale cohort with over 100,000 ETH remains profitable, and their Realized Price at $1,290 suggests further bearish price action is needed before a retest may be significant. Currently, ETH trades around $1,500, down over 16% in the last 24 hours.

On-chain data shows the Ethereum Market Value to Realized Value (MVRV) Ratio has plunged recently. H...On-chain data shows the Ethereum Market Value to Realized Value (MVRV) Ratio has plunged recently. Here’s what this could mean for the ETH price. Ethereum MVRV Ratio Has Declined To 0.87 Recently In a new post on X, the market intelligence platform IntoTheBlock has discussed about the latest trend in the MVRV Ratio of Ethereum. The “MVRV Ratio” refers to an indicator that keeps track of the ratio between the ETH market cap and realized cap. Related Reading: Bitcoin Keeps Rebounding—But Is Momentum Really Turning Bullish? The realized cap here is an on-chain capitalization model that calculates ETH’s total value by assuming that the ‘true’ value of any coin in circulation is equal to the price at which it was last transacted on the blockchain. What this model represents is the amount that the investors as a whole have put into the cryptocurrency. In contrast, the market cap, which measures the total valuation of the supply at the latest spot price, indicates the amount the holders are carrying in the present. Since the MVRV Ratio compares these two models, its value essentially tells us about whether the investors are holding their coins at a net unrealized profit or loss. When the ratio’s value is greater than 1, it means the average investor is in the green. On the other hand, it being under the mark implies the dominance of loss in the market. Now, here is the chart shared by the analytics firm, that shows the trend in the Ethereum MVRV Ratio over the past decade: As displayed in the above graph, the Ethereum MVRV Ratio has witnessed a correction recently as the cryptocurrency’s price itself has gone through a drawdown. The indicator is now sitting at a value of 0.87, suggesting the average wallet on the network is holding a net loss. The degree of the loss isn’t small, either, as the current value of the metric is the lowest that it has been since December 2022, at the tail-end of that year’s bear market. While the situation is bad for the investors at present, the recent plunge in the MVRV Ratio could actually turn out to be positive in the long term. The reason behind this is the fact that uptrends generally get the most resistance from profit-takers, with the degree of selling only becoming higher the more gains that the holders get into. Related Reading: Dogecoin To $0.57 Or $0.06? Analyst Says DOGE’s Fate Hinges On This Level When there aren’t many above-water holders left anymore, the chances of a selloff with the motive of profit-taking happening drop off. In these conditions, the asset’s price can be probable to reach a bottom. Thus, as the MVRV Ratio has tanked for Ethereum recently, it’s possible that a low could be near. Though, even if a bottom is close, it’s uncertain how long the asset would spend there before bullish momentum can renew. ETH Price Ethereum has retraced to the $1,550 level after a crash of around 12% in the last 24 hours. Featured image from Dall-E, IntoTheBlock.com, chart from TradingView.com

ETH is now correcting losses and might face resistance near the $1,620 zone. Ethereum failed to stay above the $1,620 and $1,550 levels. The price is trading below $1,620 and the 100-hourly Simple Moving Average. There is a connecting bearish trend line forming with resistance at $1,615 on the hourly chart of ETH/USD (data feed via Kraken). The pair remains at risk of more losses if it fails to clear the $1,620 resistance zone. Ethereum Price Recovery Faces Resistance Ethereum price failed to stay above the $1,700 support zone and extended losses, like Bitcoin. ETH declined heavily below the $1,650 and $1,620 levels. The bears even pushed the price below the $1,550 level. A low was formed at $1,410 and the price recently corrected some losses. There was a move above the $1,550 level. The price climbed above the 23.6% Fib retracement level of the downward move from the $1,815 swing high to the $1,410 low. However, the bears are active near the $1,620 zone. Ethereum price is now trading below $1,620 and the 100-hourly Simple Moving Average. On the upside, the price seems to be facing hurdles near the $1,615 level. There is also a connecting bearish trend line forming with resistance at $1,615 on the hourly chart of ETH/USD. It is close to the 50% Fib retracement level of the downward move from the $1,815 swing high to the $1,410 low. The next key resistance is near the $1,660 level. The first major resistance is near the $1,720 level. A clear move above the $1,720 resistance might send the price toward the $1,820 resistance. An upside break above the $1,820 resistance might call for more gains in the coming sessions. In the stated case, Ether could rise toward the $1,880 resistance zone or even $1,920 in the near term. Another Decline In ETH? If Ethereum fails to clear the $1,620 resistance, it could start another decline. Initial support on the downside is near the $1,540 level. The first major support sits near the $1,505 zone. A clear move below the $1,505 support might push the price toward the $1,420 support. Any more losses might send the price toward the $1,380 support level in the near term. The next key support sits at $1,320. Technical Indicators Hourly MACD – The MACD for ETH/USD is losing momentum in the bullish zone. Hourly RSI – The RSI for ETH/USD is now above the 50 zone. Major Support Level – $1,540 Major Resistance Level – $1,620

Despite a recent temporary 22% drop in Dogecoin's price yesterday, potentially related to &quot...Despite a recent temporary 22% drop in Dogecoin's price yesterday, potentially related to "Black Friday" rumors, the cryptocurrency has partially recovered. However, it's still down around 11% this week, putting it in a delicate position. Crypto analyst Kevin (@Kev_Capital_TA) notes a "clean bullish divergence" on the daily chart. Dogecoin briefly dipped below a key ascending support line from mid-2023, but closed above it near the $0.138 mark, a level also coinciding with the 38.2% Fibonacci retracement. This recovery, despite a lower intraday low, shows the RSI climbing, similar to a divergence seen in Bitcoin's chart. This suggests Dogecoin's momentum might be stabilizing after a prolonged decline from its December high of $0.48. Another analyst, Charting Guy (@ChartingGuy), highlights Dogecoin's return to its weekly 200 EMA zone, around $0.13, and its overall uptrend. His Fibonacci analysis suggests DOGE could close above the 0.382 Fib level, potentially indicating continued bullishness. Failure to hold above $0.15, however, could lead to a drop back to lower support levels, including the 23.6% retracement near $0.09 or even the 13.6% level around $0.07. Potential resistance zones include the mid-$0.20s (61.8% Fib), high-$0.30s to low-$0.40s (deeper retracements), and a retest of prior highs above $0.40, potentially pushing it toward the 88.8% Fibonacci near $0.56. Market volatility remains high due to ongoing US President Donald Trump's tariff policies. At the time of publication, DOGE traded at $0.149.

Cathie Wood's ARK Invest reacted to the latest US trade tariffs with a mixed strategy, offloadi...Cathie Wood's ARK Invest reacted to the latest US trade tariffs with a mixed strategy, offloading shares of its spot Bitcoin ETF while increasing its position in Coinbase. ARK acquired $26.6 million worth of Coinbase (COIN) stock since President Trump announced new tariffs on April 2nd, including $13.2 million on April 7th and $13.3 million on April 4th. Simultaneously, the firm sold $12 million of its ARK 21Shares Bitcoin ETF (ARKB) on April 7th. This significant ARKB sale is one of the largest daily sales by the firm. These recent sales follow several others in the preceding months, totaling $3.5 million in January, $8 million in March, and $8.6 million in February. Despite the ARKB sales, ARK's Next Generation Internet ETF (ARKW) still holds $142 million in indirect Bitcoin exposure through its ARK Bitcoin ETF Holdco, which is the fund's largest position by market value. Bitcoin ETFs generally experienced significant outflows, with over $273 million in combined sales in the past three days. This follows $207 million in global outflows last week and a further $109 million in outflows on April 7th. Though Bitcoin ETFs are bleeding overall, ARK remains a notable exception, having recorded $146 million in inflows for 2025 so far. Other major players like BlackRock and ProShares also boast positive year-to-date inflows.
