Yeah they are already rich as hell so why would stake or primedice would want to get funding.
I mean look at the funding from other places, they do not get above couple thousand at most. Primedice is a place that has been around since forever and they got like couple bitcoins per wager for a long time while bitcoin was incredibly low priced as well, betting 10k on primedice was much different back in the day than today, it took hundreds of btc to do that. Which means they made so much money from those days that it worth incredibly more today.
They literally got scammed 2000 bitcoins from a seed hacker and still continued their way. They do not obviously need any funding at all because they have been making like a bank forever and what we can offer as a bankroll would be lower than what they have let alone be more than what they need.
No one is too rich, the whole reason people get successful and more so is simply because they are hungry for more success.
There may be no good business reason now for these guys to seek more funding, but who knows? So many good reasons to want more funds. If Telegram even wanted an ICO and had good reason, why not? See all the amounts they raised, guess investors thought it was a good idea too.
For casinos, it's simply expansion. Maybe they want to grow even bigger and take over the gambling world online
There is a huge difference between getting an investment and getting your bankroll invested. One is getting money to expand bigger the other is so you can get less risky while running a casino. Primedice or stake wouldn't do bankroll investment because honestly they have so much money that they do not need bitcoins to cover for the bankroll, what you are talking about expanding is not there because its just getting bankroll investment help, not funding.
They could get their websites funded by people (and believe me it would take just 1 day to reach to tens of thousands of bitcoin funded) and then go out and use their own money to get bigger but they are already doing that as well, look at stake its brand new compared to primedice, they literally used their own money to fund primedice then made profits and used it to open stake so they literally do not need any help from us.
