In summary the article concludes:
"Its a steep mountain to climb with considerable risks and failure more likely than success."
Dude i heard all this when i first got into BTC. When it was under $20 nobody cared. Then once it became worth something, the warnings come out...just like yours above.
Crypto is risky, be it BTC, ETH or THE DAO, your fiat will go up and down alot.
Most investors are aware of this before investing.
So thanks for heads up and gd luck with your own investment choices.
