ETH is already on 2nd position on coinmarketcap and JPM coin is effecting XRP but not for long by my point of view xrp eth bitcoin are old cryptos and BTC is the base crypto. Q3 and Q4 of 2019 looks bright for crypto currencies. ETH is getting stronger while update fork is coming near.
JPM coin affected XRP, really?
They are both come from financial companies, but I don't think JPM might have effect on XRP.
ETH will steadily stay at the second position on CMC for years to come.
There will not have any flippening in the second position in next few years.
