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?
for now btc and eth are indeed the best in the cryptocurrency world, and the great thing is that almost all altcoins now use the eth platform.
even so. I am sure that there will be a coin that can replace the position of btc and eth, but with the coin note it has to work harder to find big investors and other platforms that want to work with the coin.
Btc will stay on top as it is now. In future, there maybe some other coin which will have a better blockchain features than the ethereum blockchain, only that could replace ethereum if many new coins accept that coin’s blockchain as their platform and this is not going to happen in next few years.
