Bitcoin (BTC) begins the last full week of April juggling fresh US-Iran war fears as resistance hurdles line up. Key points: Bitcoin stays green on weekly time frames with multiple nearby price levels in focus. Elliott Wave analysis concludes that $81,000 is Bitcoin bulls’ next “final boss.” A resurgent US-Iran war threatens to unravel last week’s crypto and risk-asset gains. Bitcoin ETFs see major inflows, but investors’ cost basis is still above $80,000. Bitcoin’s true market mean metric reveals that the current bear market remains “mild.” BTC price can still make “new highs” this week Bitcoin still managed a “green” weekly candle despite last-minute sellers driving price below $74,000. Data from TradingView shows a modest recovery ensuing as the new week begins — despite the lingering threat of geopolitical escalation between the US, Israel and Iran. Price now has multiple resistance levels overhead, with the nearest being its 21-week exponential moving average (EMA) at $78,400. Over the weekend, trader and analyst Rekt Capital stressed the influence of that trend line. “Bitcoin is rejecting from the 21-week EMA (green),” he noted in an X post alongside a print of the weekly chart. “It is this rejection that could force a post-breakout retest of the top of the Double Bottom (~$73k) next week, provided Bitcoin Weekly Closes just like this.” In a subsequent post, Rekt Capital said that a successful retest of the $73,000 area would “confirm the breakout” for the bulls. #BTC — Rekt Capital (@rektcapital) April 19, 2026 A Weekly Close just like this could confirm the 21-week EMA (green) as resistance to set up for a post-breakout retest of the Double Bottom formation top (blue ~$73k) A successful retest of the Double Bottom formation would confirm the breakout$BTC #Crypto #Bitcoin https://t.co/7eZiVYZFeQ pic.twitter.com/cWxH3lMNpb Continuing, trader CrypNuevo forecast that BTC/USD would continue to trade in a range with an $80,000 ceiling “for the next month.” They acknowledged that it was “unknown” how high the pair could go should the US-Iran war definitively end. Crypto trader Michaël van de Poppe, meanwhile, remained upbeat, seeing a push beyond last week’s local highs next. He noted that there was a new “gap” open above price in CME Group’s Bitcoin futures market. “Relatively strong bounce upwards on $BTC on Monday, as markets tend to go risk-off prior to the open. Gold has gone down, so no attached risk,” he told X followers on Monday. “Bitcoin bouncing upwards, and given that there's still a gap to $77.3K, I would assume we're going to see new highs this week.” $81,000 emerges as Bitcoin’s “final boss” In its latest BTC price analysis, crypto market intelligence platform Decode placed specific emphasis on $81,000 as the resistance level to beat. As part of Elliott Wave analysis, Decode showed BTC/USD trading between the 200-week and 21-week EMAs. “Bitcoin still pinned below the 21 week ema, but looking pretty good overall, and with the final boss at 81k,” it commented. This “final boss,” Decode explained in subsequent debate on X, “narrows the options from an Elliott Wave perspective, removing short term bearish counts.” $81,000 also represents the average entry price for institutional buyers of the US spot Bitcoin exchange-traded funds (ETFs). Nearby, the cost basis for Bitcoin’s short-term holders (STHs) — entities hodling for up to six months without selling — is now at $83,500, per data from onchain analytics platform CryptoQuant. CryptoQuant notes that the STH spent output profit ratio (SOPR) metric — the ratio of STH coins moving onchain in profit or loss — is circling breakeven. “If SOPR manages to sustainably move back above 1, it would indicate that STHs are once again realizing profits, which is generally positive for the market as long as values do not become excessive,” contributor Darkfost wrote in a “QuickTake” blog post last week. Iran war comeback risks risk-asset “unwind” The US will release little by way of macroeconomic data in the coming week, but markets have bigger concerns. With the sudden comeback of the US-Iran war, traders are suddenly revisiting the prospect of higher oil prices and a longer-term knock-in effect on inflation. “The sudden change in events has characterized the Middle East conflict since it started at the end of February,” trading resource Mosaic Asset Company commented in the latest edition of its regular newsletter, “The Market Mosaic.” “And it appears that intensifying hostilities could unwind the bullish action over the past few weeks.” WTI crude oil fell to its lowest levels since early March last week as markets increasingly bet on the ceasefire and agreements between the US and Iran holding. The fresh breakdown in diplomacy sparked a rebound toward $90 per barrel.

Continuing, however, Mosaic warned that the writing was already on the wall for the equities rally after the S&P hit fresh all-time highs. “Simply following breadth, sentiment, and positioning by institutional investors helped flag the recent rally. At the same time, warning signs were already emerging as the S&P 500 broke out to record highs,” it wrote. “The number of stocks breaking out to new highs is failing [to] confirm the move in the indexes, while buying pressure from a key group of institutional investors has largely run its course.” As Cointelegraph reported, oil prices in particular are under the microscope as a US inflation catalyst. The next print of the Consumer Price Index (CPI), which will reflect the ongoing impact of the war during April, is due for release on May 12. Risk-on institutions wake up to Bitcoin The upshot in risk appetite amid Iran relief had a near-instant impact on Bitcoin institutional investment vehicles. In particular, the US spot ETFs saw considerable capital inflows through Friday, with more than 25,000 BTC entering over five days. “The latest accumulations by spot ETF firms are significant, as the last time they posted a figure this close was in April 2025, when they added 23,900 units,” CryptoQuant noted in a “QuickTake” blog post on the topic. Data from UK-based investment company Farside Investors confirms that on Friday alone, the net inflows to the ETFs were more than $660 million — the largest single-day total since January. “Aside from the current milestone, BTC spot ETFs are recovering,” CryptoQuant continued. “The balance held by the firm offering them has been declining since October, but has risen since the February dip.” In BTC terms, the ETFs’ total holdings are now at their highest since November 2025.

Yet, $BTC has failed to reclaim the ETF cost basis (~$81k). Let's watch... pic.twitter.com/qVD76JobLY Commenting on X, Andre Dragosch, European head of research at crypto asset manager Bitwise, acknowledged that ETF investors’ cost basis is still above spot price at $81,000, increasing the psychological significance of that level as a resistance hurdle. Bitcoin price downside still on “milder path” The average Bitcoin hodler remains underwater despite the recent trip to ten-week highs for BTC/USD. Related: Bitcoin can grow 'probably a lot bigger' than $30T+ gold market — Analysis New research from onchain analytics platform Glassnode also warns that in terms of history, Bitcoin’s current bear-market drawdown remains “mild.” In an X article published on Thursday, lead analyst CryptoVizArt used the true market mean (TMM) metric to assess hodler profitability. TMM filters out long-dormant or lost coins to provide a more accurate picture of cost basis for the active BTC supply. “When BTC trades below TMM, the average active holder is underwater. Since 2016, this has happened ten times with meaningful negative outcomes — episodes lasting from 2 days to over 11 months, with max drawdowns ranging from -0.1% to -57%,” they summarized. Bitcoin is now over 75 days into its latest sub-TMM phase, with TMM itself at $78,200. A chart plotting 2026 against Bitcoin’s historical average dips below TMM shows price forging a “milder path” than before. “That said, 75 days is still early. The 2018 and 2022 episodes didn't bottom until months 5-9,” CryptoVizArt warned. “The signal isn't ‘all clear’ — it's ‘watch closely.’ Reclaiming the TMM and stabilizing there would mark active investors returning to profit, historically a strong reset point for momentum.” This article is produced in accordance with Cointelegraph's Editorial Policy and is intended for informational purposes only.
