How do you find these coins that are possible to 10x?
Research and hearsay. A lot of successful investors (I don't consider myself successful since I'm sure there are people who are making WAY more than I am) will tip some coins to you.
When you hear those coins, you should research them. I have done that, and have come to this conclusion.
The lack of marketing for these coins is stifling them. A barrier that could be removed at any moment..
