The best time to buy is a few months ago when the world was shaken, but if left behind it is now quite right to buy. Both Bitcoin and Altcoin are good
we do not know what kind of potential could bring future coin prices. besides, no one can guarantee the right time to increase the number of assets we have. we do not know, whether, in the near future, crypto prices will go down, or go up. buy it now remains a risk. but, that's a decision you need to take, because when prices go up, now is the right time, and vice versa.
