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?
in my opinion, it's not impossible for a coin that costs $ 1 then the price goes up to $ 10 or $ 50, now it's just how we see the development of the coin because a lot of coins that are worth $ 1 become no price at all.
You are not right here. Many investors manage to make millions on the cheap but very good altcoins. They simply operate with large volumes of these tokens. Take, for instance, Cardano or TRON - they are really great but inexpensive.
