What's your opinion on buying new emerging coins that are not yet on top and cost less than 1 dollar?
How do you decide whether they have potential to grow or not?
We can always look for the past performance of that coin if it has a potential to grow.. Though the price is 1 dollar or below that doesn't mean that it would not grow.. I think it's best to buy that coins in a very low price and experience it growing rather than buying it high and then drown..
Some of the penny altcoins have already shown the tremendous growth. They gained much more than the alts from the top-100. Yes, it is worth investing in them.
