I agree that losing bitcoin by investment is a good learning experience. I have played around bitcoins for years and i have lost a lot a lot. I have invested in shares of some companies and the shares are now barely worth anything. I also have invested in HYIP, casino, alt coins etc. Most of them ended up in losses but at least now i know how to move forward too.
Anyone should also have this thinking or much better for this one.
No one become rich in gambling and I know it, unless you can cheat in gambling I think you can win, but most of the time we are loser.
And for me, investment is much better than to gamble. It is much safer to put your money if you want to gain profit.
