Bitcoin rebounded above $68,000 but could not hold gains after failing to settle over $68,800. BTC is trading below $67,200 and the 100-hour simple moving average, with chart signals pointing to renewed downside risk. Key levels highlighted include resistance at $67,800 and $68,500, and support at $66,000 and $65,500.

Bitcoin finished March up 2%, ending five straight months of declines, and opened April near $68,250. Analysts are watching a heavy supply zone at $70,000–$72,000, where about 650,000 BTC were accumulated and may be sold if holders reach break-even. Key downside reference levels cited include the 200-week EMA near $68,300, the 200-week SMA at $59,400, and realized price around $54,000.

Concerns about whether quantum computers could eventually compromise Bitcoin have resurfaced, as discussions focus on signature security and the network’s ability to adapt. The debate points to Satoshi Nakamoto’s only public comment from 2010, outlining how Bitcoin could respond if quantum breakthroughs arrived suddenly or gradually. Analysts also cite today’s hardware limits, contrasting ~6,000-qubit systems with estimates that far more stable qubits would be needed to threaten modern cryptography.

Morgan Stanley filed Amendment No. 4 to its Form S-1 with the SEC on April 1 for the Morgan Stanley Bitcoin Trust, a spot bitcoin ETF proposed to list on NYSE Arca under the ticker MSBT. The filing describes a passive product tied to the Coindesk Bitcoin Benchmark and reiterates a 0.14% annualized delegated sponsor fee, while outlining custody by BNY Mellon and Coinbase Custody and updated mechanics for share creation and redemption.

On March 31, BlackRock filed Amendment No. 1 to a Form S-1 with the U.S. SEC describing the iShares Bitcoin Premium Income ETF, a product that pairs bitcoin-linked exposure with options-based income.

Bitcoin’s average deposit size sent to centralized exchanges rose sharply, with the mean Exchange Inflow reaching 2.62 BTC. The move is described as an uncommon level that has historically shown up during stressed market conditions, while BTC was last noted trading around $68,500.

QCP Group published a note assessing quantum-computing risks for crypto after a Google whitepaper dated March 30 argued Bitcoin-style elliptic-curve cryptography could be broken with fewer quantum resources than previously believed. The firm says the issue is a long-term, system-wide challenge tied to public-key infrastructure rather than an immediate market shock, while noting BTC was trading in the high $68k range at the time of writing.

Crypto analyst Sykodelic said in an X post that Bitcoin's "bleed" is close to ending and argued BTC is unlikely to fall into the $40,000 range, pointing to how 2022 dip buyers waiting for $12,000 were sidelined. He outlined a scenario around a deviation near $60,000 and a potential move back above $74,400, while Willy Woo separately flagged model-based bottom estimates between $46,000 and $54,000. At the time of writing, BTC traded around $68,600, up over the past 24 hours.
