How do you decide whether they have potential to grow or not?
You people should understand better that this is not about the price of each coin but it is about the market capitalization of a coin or its value as a whole. There seemed to have lots of coins under $1 here but in reality it is already expensive. Try to look at the details of the coin guys before saying anything.
Don't ever under estimate those coins under $1 because if you hodl those coins the potential might be great for longer terms. Yeah you're certain for that its not all about the price, but the most important is the community it has and the development of the currency really matters. The demand may rise particularly if this coins will become more popular in the entire cryptocurrency world.
