I think that now is a good time to invest in those coins that are in the TOP-10. These coins are the most reliable, but they will not give a very big profit.
in fact, it seems to me the most win-win strategy, it is an investment in the most rated coins. But among them you still need to make a choice if you have a limited budget. I believe that it is better to choose in favor of that coin, which has a price of about 1 dollar.
