Yes, in my opinion, now is the right time to buy Altcoun because currently the price is cheap, when the cheap price is definitely HODL time, but it is also a good opportunity to buy when the price is cheap and start the investment again.
Most altcoin are very cheap compared to the beginning of 2018 so this is a good time for investors to buy altcoin to prepare for the growth period of late 2018 and early 2019. more volatile and I believe it will explode in the last months of the year. Hopefully there will be a new uptrend season in the cryptocurrency market.
