Hi,
Quick explanation. We had a bug report today (first time in 3 years) on crash game. It will be fixed within few hours.
Bitcoins from your bankroll can't be stolen because we use hot & cold wallet + all withdrawals have to be approved. The user which had a 10BTC win started with 0.00001BTC and was intentinaly exploiting the site and of course that client is not obligated to payout that.
for how long are you offering the crash game? 3 years?
hot wallets were very often hacked as far as I know so why do you think yours cant be hacked and be stolen?
I would anyway feel only good with manual withdrawals
