If you have the patience for long term holding, then current low prices are a good chance to buy good coins at cheap prices. It is safer to buy top ranked coins.
I think that every person here should have some coins for long-term holding. With patience it's easier, people without patience can
buy some coins, store them and forget about them while they have other obligations.
This is the bottom! Chances that we will see the prices lower then now are very low, and with time they are getting lower. When
crypto-market start rising again people will regret this missed opportunity for buying cheap coins.
