Doesn't the term 'whistleblower' apply to someone who worked at a company and screwed them from the inside by reporting their illegal activities? This is why I feel that you aren't considered a whistleblower op.
You are completely wrong, any body can be a whistleblower, doesn't matter if the person works in the firm he or she wants to expose or not, what really matters is that, you know what is been hidden and can expose it accurately in details without mistake or misinformation.
And Secondly, as a vip player on Bitcasino who is close to the management of the casino, including the CEO of the casino himself, op is as good as someone who works in the casino, an insider as you said.
Also, no casino(Especially crypto gambling sites) out there is 100% transparent thanks to their constantly changing T&C. Understood your rant, but your post won't really change anything.
And again, you are wrong, such experience as shared by the op changes alot of things.
First is, as someone intending to play on this casino, reading such experience from a high roller begins to give you reasons to doubt the trustworthiness of the casino, specially if you are a high roller yourself, you don't want to get yourself involved with a casino where your contributions to the growth of the casino won't be regarded or appreciated.
