as we know now Ripple has taken the position of Ethereum (ranked 2 in the coinmarketcap), and will this change everything in the future? My point is that Ripple replaces Ethereum whether there will be major changes in the future, such as whether all ICOs will use Ripple as a payment from their ICO to replace payments using Ethereum and all exchanges will use Ripple (XRP) as a payment to buy or sell altcoins on the exchange.
if I think that can happen and what do you think? please give your opinion.
yeah,, ripple now replaced ethereum as the best altcoins,,
but, i think everything will not change, because this ripple become the second biggest crypto just for a while my friend.
soon or later ethereum will be back and become the best altcoins again

Hopefully Ethereum will rise again in the near future. Some time ago Darren Langley introduced Ethereum 2.0, which includes innovations including Casper and sharding, being built in a decentralized manner
"It has organic qualities that hopefully will contribute to how human organizations can improve but remain inclusive," "Darren Langley"
