- As long as the amount of liquidity of a coin in the exchange is high, I can say that anyone's trading activity can do that. Of course, why would you buy a coin in crypto trading if you see that there are not many traders buying, these scenarios are just common sense.
It's like this, you buy coins that you know people have demand for but if there is no demand simply don't buy it, that's as simple as that so you can get a profit.
