Investing in a low price coin will be a good idea, I am sure he can find so many potential low price coin which can increase in anytime. But he needs to be careful to select the coin because, with so many options, he can pick the wrong coins list. He needs to check one by one of the projects, especially for the new coins because the new coins always tempt us to buy but we don't know how good they are. Maybe he can choose the low coin price which is in the top 100 coins list so he can see the chance for each coin to increase.
