I've got a few coins on the side and I'd like to make them work.
Which gambling site do you advise me to invest in the bankroll?
You can deposit them on poloniex and use their lending feature. The rates are not stable, but you can easily get an average of 0.15% of your investment. It doesn't sound like much, but depending on the ammount you have to invest, it can be quite profitable. I know it's not casino but it looks safer so maybe you should consider it as well.
But it seems that there is no need colaterral so everyone can scam here too. I do not know if this is really afforable since no collateral, it is pretty hard to guarantee our money there although there is huge traffic on their site and huge money there. Did you even try it before suggesting to us? Many of us does not really know how it works
