Now the mainstream currency, BTC-ETH, has the upper hand, and they have the strength and technology, but the future is likely to be a new project to replace them more mature and more comprehensive. What do you think it would be?
BTC-ETH pairing is the most higher volume in trading and I don't think that this will end-up easily. Even if many new coins will come this will not make a threat to bitcoin because Bitcoin will remain as the main currency in cryptocurrency as all price of altcoins will be affected with the price movement of bitcoin thru algorithm.
as manybpeopel as manybopinions, so i thinkbthatvit is hard to say, maybe ethereum andbitcoin, but they are incomparable
