Which coin is the best to keep than money now?

Taking into account the current bearish market, XRP shows better patterns and seems to be resistant to the general tendencies on the crypto market. After displacing Ethereum, Ripple remains the second biggest coin by market capitalization. Also, I consider Stellar and EOS to be worth attention.

As long as every coin is subject to volatility then it not advisable to keep in place of money.

Fiat is safer than any cryptocurrency for now except for maybe later in the future but as for now i will not advise you to keep any coin instead of money.

The best coin to keep now better than most of money is bitcoin coin because when the market grows you will earn more money than keeping money which will not give you profits.
