So, maybe the winner may not even share if they win something, it may look like "just 500" for all that trouble but we all know that's a lot of money for a lot of people and begging even 50 bucks is like a full time job because if you find a few people who can pay you that, which you won't, you are set for the whole month in some nations.
Either way, you should never brag about how much you've won, certainly not here on the Internet via forums or chats. There are enough companies that specialize in finding out the true identity behind forum accounts. If an account writes about how much he or she has won, this can be a real problem in "real life".
For example, I know a few people who were attacked by the Ledger hack last year. A text message with "I know where you live, transfer me 1 BTC otherwise I'll get your wife" is enough ...
I don't think we no need to worry about our identity even if we share our casino wins which can be even in millions unless the database of the casino got breached. No one is going to be in problem if they say he have 1 million dollar worth of BTC in his wallet because this is an online forum so its really not a difficult task to proxy our IPs but be careful while chat with someone on social media because you have been under surveillance for 24/7 by Mark and others.
