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?
There are more coins now that can be the new king.. because many coins now are after to Bitcoin and Ethereum because the price of both Bitcoin and Ethereum is going dump day by day. So many coins that at the top 10 can beat those two soon, i think maybe 3-4 years.
