Who is the best Bankroll among this sites and why?
Bitvest, betking, primedice, bitsler, bit-exo, luckyb.it and Crytogames or other Bankroll site.
I'm new here and looking for right information cause I want to invest my 0.5 BTC on it.
I'd say that Betking would be your best bet. They have been proven to be the best profiting casino over a timeframe of 3 months I think. You can get this info online.
Bitsler doesn't even offer an investment function, i don't think.
