cryptos are way over rated. way to many downfalls. prices need to level out right about where they are now, or slightly lower. And grow it like a brand, not a fad. Steem, bitcoin, litecoin, and maybe monero should be safer long term bets if you buy low , or all hell breaks loose. Key thing to remember is electricity is needed for cryptos, so in a storm, blackout, martial law, solar flare, and more. You will not be able to use it in times of need. (most likely)
