I'm thinking about investing in bustabit's bankroll but I wonder how safe the funds are? Can the funds be hacked at some point in the future? How are they stored?
Most funds (>95%?) are stored in a cold wallet afaik so you have to trust devans that he won't abscond with the money or that he won't get himself into trouble that could result in him losing access to the site's funds. He has been running bustadice since October 2017 and bustabit since Feburary 2018 and hasn't given any reason to be distrusted.
There was one hack
last year but only the hot wallet was drained and devans reimbursed the losses from his own pocket.
Out of all bankroll investment opportunities I consider bustabit/bustadice the safest.
If memory serves correct I think there was also a safety mechanism in place allowing funds to be retrieved if need be by using multi-sig wallet. Please correct me if I am wrong and devans has an excellent reputation.
The manner in which he dealt with the hot-wallet hack you mentioned was commendable because he covered the losses himself and re-opened the site very fast after finding/fixing the issue.
