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?
The price of coin does not matter. It is important that the coin has no potential. Find out the project development team, PR plan, road map. If all is well then that coin is very potential, it is worth your investment. I will give you a coin in the top 10 coinmarketcap which worth less than $ 1 is Cardano (ADA)
