There are few cryptocurrencies other than bitcoin that will be Monero, Ethereum, Litecoin and so is preferable for me.
Except a dark coin like XMR, all of them look to have gone centralized because of big scale investors who have the capacity to eat up the limited supply. As of price, I think Eth stands a good chance only if institutions decide to shift their money from btc to it and that will not happen so soon because they will need others to join the party and so they are drawing everybody's focus to btc.
