I keep a significant portion on gambling sites and the others in cold storage. Gambling sites are a great way of generating almost guaranteed profits due to the house edge. However, not all are trusted. I invest funds mostly in moneypot and the others in satoshidice.
Yeah pretty much the same as me, I'm currently investing Bitcoin and Dash in Crypto-games casino.
Generating some pretty good ROI at the moment.
Haven't tried Moneypot myself, but might try that soon.
