The cryptocurrency market is experiencing a potential 'altcoin-only' bear market, with all coins except Bitcoin (BTC) following a classic cycle. Analysts note a significant difference this time, as Bitcoin ETFs are attracting substantial inflows. Concerns are rising regarding the viability of certain altcoins, with some commentators suggesting that chains like Solana ($SOL) are on the verge of collapse. Investors are advised to reassess their risk exposure, particularly if Bitcoin's price were to drop into the $40,000 range. The sentiment among some insiders is that many altcoins are lacking fundamental value, with predictions that they may ultimately trend towards zero.
