Yes MAN and WAN are unpopular coin and even most people have never heard of it. the determinant of a successful coin is how popular the coin is. I think that the more popular a coin the more comfortable and profitable it can be. While the unpopular coin will be difficult to develop and usually if there is a bad news then the coin price will decrease drastically. investing in an unpopular coin will have enormous risks, so we must take the decision and be ready to accept any risks that may be incurred.

I think with the increasingly widespread crypto market then choosing a coin that is in the top 10 will give us comfort in investing. The risk of losses will be quite small compared to other coins that are beyond the top 10.
