I personally think that the cashback system plays the most important role for a casino site nowadays. Because almost all gamblers lose their bet at some point of time while playing gambling, in this case gamblers will be most attracted to the site if they are given some percentage cashback of their loss amount. i think this is a potential strategy. Because I myself personally look for such sites
In fact not many bitcoin casino offers cashback, most bitcoin casino offers rakeback. I myself prefer to have rakeback than cashback, because rakeback gives players something back based on the wagering activity regardless how is the overall profit. It means that losing and winning players will still get something back. Cashback might be something attractive for whales but for small player like me, the amount of cashback wont be big since I wont lose big amount of money, that's why rakeback is a better one than cashback.
as I support you here mate , I love seeking for rakeback giving site than any bonuses offering because with rakeback I can feel the generosity of each site i Played than their obligation .
and also this keeps giving me another amount to start as capital once I lose all my budget for a certain time and managed to make it grow from scratches .
