I believe that you should not keep all your money in any one coin, because if something happens to it, any unforeseen situation and you lose all your money. Divide your savings between the most popular and promising coins, so you reduce the risk of losing all your money in an instant. In which coins to store savings? I prefer Bitcoin, EOS, ETH, Zcash, Stellar, TRX and 10% of all the money in tokens of new projects and coins, which are now little known, but have great potential for growth.
