ok, i was being funny.
$50 bucks? Bitcoin and ethereum are no brainers but that $50 bucks will not earn you generational income buying eth, btc.
You have to buy a cheap ass coin and but lots of them. $50 will not put you in the game if you invest in btc, eth. $50 bucks in another cheap ass project will do the following...
1. Get you engaged deeper in the ecosystem
2. Education on this industry
3. A great experiment that will pay dividends down the road with the knowledge you gain
4. and possibly a great 100x return
2018 is the year of the privacy coins/projects. Throw that $50 into one. Check out electra (eca)
