Bitcoin fell to $66,000 on Tuesday, erasing last week's gains.

- The drop came after the US government moved $2 billion in Bitcoin, raising concerns about possible selling pressure.

- BTC lost up to 5%, but partially recovered.

- Solana (SOL) fell 6% despite Monday's gains.

- Ether (ETH) showed relative resilience with a 1% decline despite outflows from new ETFs.

- Other major cryptocurrencies also suffered losses: ADA - 5%, DOGE and BNB - 4%, XRP - 3%.

Analysts warn of possible further losses due to macroeconomic decisions and the lack of new catalysts.
