Yes, Bustadice is one of my favorite betting site. Although we see many new gambling sites each day, but the old is old and the gambling experience which we get while playing Bustadice is just great and not comparable to any of the new sites in the market.
New sites and old sites can't be compared. If its the trust related issue, definitely people would love to deal with the old sites that has reputation and won't gamble with the new ones. Let's say they might gamble with the new ones but it is just for testing purposes and there's no intention of trusting it from the very first time. Happy to see people like you to say that bustadice is one of your favorite place to gamble.
People play here because the owner is the most honest and most perfect owner out there and there is not a single owner that I can say is better than this one. If you are a casino the people that gamble look for trust first, we are already against house edge so we do not want shady business owners on top of that but bustadice is just so trustworthy I would trust it more than a decentralized trustless place.
With that said, you can actually be part of their bankroll by investing. Another one, is you are secured that bustadice has their funds covered by the owner and it is very highly likely that they will never run out of funds.
