I never imagine bitcoin to be replaced on the number one spot since it will always be the king and will be considered as valuable than gold. No one knows right? Ethereum had been replaced already by ripple which most of us dont agree with that. I gave my vote to ethereum since it has all the potential to replace bitcoin among those altcoins you provided. I am still looking forward with ethereum 2.0 upgrade.
Ethereum didn't got replaced yet. Which ICO using XRP as their platform if may i ask? ETH only beaten by total marketcap, you should try to look 24 trade volume between ETH and XRP.
I think Bitcoin's cash is very good, first because its technology is very advanced, and secondly Bitcoin cash has a very strong team to support its operations.
Yea, and don't forget whose fault has made bitcoin fallen from $6k to $4k? It's because BCH!
