You know...I just got into this myself, mainly because in my state sports gambling isn't legal yet and the sports book I want to place bets with really only accepts bitcoin.

I put in $500 on Friday, unbeknownst to me, that there's a 3-day hold after using a card. Didn't get to place my bets last night.

However, opened my Blockchain this morning and I've gained a 15% increase.

I certainly wouldn't put in what I can withstand losing, but looking at my savings account that makes peanuts every year, it is a very tempting option.
