The idea I did is invested like small money (50$) in some small coins... And you really need one to do good. I got 20k Doge couple of years ago for some change money and look how good it did. But most of those coins don't do well, have that in mind.
Wow, this is amazing, because with 20 thousand Doge coins at this point someone can become a very rich millionaire, because in the past Dogecoin was really not worth anything at all so many people throw away Dogecoin without saving it at all.
The mistake which most people made is that they invest more in the low volume coins and if the coin did not perform well, all their investment is at a risk. If these low cap coins dump, its really hard for them to recover. Low cap coins can give you good return but invest very little portion of your money in them.
The only positive trading scenario when you trade low volume coins is that you set a very low buy order and a seller has to take the opportunity and dump at very low prices. You could then try to place a sell order right below the first sell order. However, this is just painful and not amusing at all to do.
