Cold, hard cash in your safe may have declined by a fraction of a penny per dollar in January given the accelerating inflation rate, but a 17% to 41% hit in the five leading types of cryptocurrencies isn't much of a consolation prize. Solana (CRYPTO: SOL) was down 41%. If it's any consolation, the last time Ethereum got off to a bad start in January it wound up climbing 21% through the final 11 months of 2019.
