If bitcoin has not eliminated its shortcomings for a long time, it is quite possible that in the long term, and not next year, Ethereum could well become a contender for the place of the leader of the crypto currency.

If this happens, and bitcoin will lose its current shortcomings, for which it is now heavily criticized, then Ethereum will not have a chance to bypass bitcoin.
