I want to ask, when is the right time to buy altcoins, help me friends, please give your best answer
The best time to buy altcoins is the time that you find convenient. For example, now cryptomarket fell so you can invest now! And by the end of 2018 there will be growth!
in any case, when a natural price fluctuation occurs, it is very profitable to invest at low levels. But when the market falls for unknown reasons, the investment is profitable, but very risky.
