I think that now is a good time to buy Altcoins, I try to monitor promising projects with good volatility, from the latter I bought AdEx.
There is no such good time to buy.You can buy whenever you want to.But one should notice when the prices are low and then only he or she should buy some cryptos.The market of cryptocurrencies is expanding day by day even though the prices are down.Cryptocurrencies are an easy way to earn a lot of money and that too in a short period of time.Cryptocurrencies can give competition to the fiat currency as people are preferring digital currencies now a days.
