Statistical research shows that most retail traders lose their money when they trade, this research was done in markets like stocks and comoodities. I would safely assume that it's even worse in crypto because there's no regulations and lots and lots of scams. But this also means that "investing" in crypto is not safe either. Some people think that if they put they money in a coin that seems like it has good potential and wait a few years, they will be in profit. But what most likely happens is that the coin will be abandoned in a few years and its value will be close to zero. So stick with Bitcoin and don't be greedy.
