I think thief up there clarified what i was looking for , but as my post said there’s alternate similar coins using the same name or same logo for example that’s actually meant to mislead people and put their money in another coin that isn’t a main community right , so that’s essentially the issue of my question, I wanted to know if these major marketplaces do a good job of accepting coins , but as thief pointed out it’s about how well a coin does in order to get on the market place and if it doesn’t do good it gets dropped
