Most of the coins has dropped before and now they are all standing the same and remain to be unstable. Go with the finest coins, bitcoin, ethereum, etc. they are quite expensive but your investment will be worth it from these coins. Invest only if you know the coin you are investing with. Make sure that you are not only investing because you want to be rich but invest because you can see the future with that coin. And that's what I can see from the leaders of crypto's.
