It is worth a try. Take $10 and find a coin that is worth 0.001 (or less)
Then buy 10,000 of them. Put them under your own private key (yes, find and download the wallet).

Then do that 9 more times. The worst that could happen is you lose $100 dollars. The best is that one of them goes ballistic and you wake up one day to $100,000.

This is meant to be financial advice, take it do it and if you mess it up, come see me.
