Also next time choose the old reputable casino to avoid this issues again.
It's ok to test new casinos but do not deposit huge money, let them prove themselves first that they are legit and they are going to stay for a long time, pick reputable sites like Bitvest to play and make it your main site site to do gambling you have a peace of mind knowing that they are the most trusted and stable gambling site in the market.
I would just add one thing, do not deposit huge money and don't keep big funds on the site, when you finish with your gambling session withdraw! If you don't take care of yourself nobody else will! I never gambled on this site, I see it's old (official thread is created in 2016), but with just 16 pages in all that time we can't say it was popular! Why to choose so unpopular site, with so many good and popular casinos?
BetBit is gone with players money, they are not active for months and do not expect to hear from them again!
