It is right, if we invest in gambling sites than it is more profitable than use your amount in gambling, Also i know that everyone who are using bitcoin they have a lot of trust on all gambling sites, So it is really good to do investment wise with bitcoin in gambling sites. Otherwise if we use other sites for investing, than they all are risky and many people are not trust on them, including me.
Will do agreed with you investment in bankroll is more profitable as we can see above the statics of OP how doing profitable for him, that is good decision to keep us on side of the house because the house know how to make profit in long run.
