Hello,
are there any new cryptocasinos with a free bonus in cryptocurrency? Find only the same casinos!
You can try rocket.run they have an event where you can get an additional bonus on your deposit. If you deposit 1BTC you can also get 1BTC for free you just have to follow the mechanics of the event.
Risky! Op clearly does not seem like he has knowledge of how these deposit bonuses work which is why you are complicating things by saying that he can acquire 1 BTC without mentioning how tough it is to actually gain thanks to the wagering requirements, KYC(Some casinos) etc.
Do your research op.
