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?
I think the new king will be some in the top 10 altcoins like XRP, BCH, WAVES, LTC, and DASH. But not to quickly to be the new king because bitcoin is the real king of the crypto and bitcoin is not easy to beat. Maybe in the next 5 years bitcoin will not be the king and some of the altcoins will be the new king!
