Some alternative cryptocurrencies (altcoins) rallied on Tuesday, albeit in a six-month downtrend. For example, Solana's SOL token is up 2% in the last 24 hours, compared to a 3% rise in BTC over the same period. Still, SOL is down 50% in the last month, compared to a 35% drop in Ether (ETH) and a 27% drop in BTC.
