Real money can be made from micro cap coins, the higher the risk the bigger their reward and not all micro caps are bad, some haven't created enough awareness for themselves and some are still in beta phase, like few new play to earn games that aren't up and running yet but the team are working, invest few hundreds of dollars and you might make insane money later.
"Can be" is a great way of saying that you could also lose all your money as well. Sure if you are invested into a micro cap then there is a chance it could go 100x that others can't, because bigger cap places can't go 100x, can you see bitcoin becoming 2 million dollars soon? Of course not, that's 100x for bitcoin and can't happen.
Whereas, something that has like 1.5 million dollars cap, could end up with 150 million dollars cap and that's nothing in crypto world, and that's why people invest. But while we are doing it, let's remember that it could also go down to zero or near zero and make us lose all our money too, that's the risk we are taking with micro caps.
