I think keeping the equilibrium aside several investors are a little upset they were not advised beforehand or maybe even consulted before the changes were made. I know you made a post explaining your reasons so I hope they would be satisfied with the explanation.
Is it really necessary to say that 5000+ BTC and 6500 BTC are significantly larger bankrolls than they need to be? Another way of looking at it is the size of bankrolls are advantages and are attractive to investors in that others would want to invest as it shows the website and its owner are genuine/trustworthy etc. Maybe a change in format should have been implemented after consulting investors so that would have eased the transition better.
I explained my reasoning for not providing an advance notice in bustabit's thread:
Having an unnecessarily large bankroll is not an advantage. For one it's an unnecessary liability. All other things being equal I'd rather be responsible for 3,000 BTC or 4,000 BTC of investors' money than 5,000 BTC or more. It also indicates that the casino is charging investors below market value. Ideally the bankroll is just large enough to support all bets that players want to place and no larger. First and foremost bustadice is a casino and its players the customers, so attracting a large bankroll is not the end goal but the means to the end of allowing our players to bet.
I referenced the explanation you gave and thanked you for it.
Anyway it seems you are going full steam ahead and from what can be seen here there are a few investors that have expressed some reservations but there is no flood of complaints or grievances. If the profits still provide a good return for investors even after dropping approximately 33% then surely they would remain rather than pull their funds out.
