as i said in tittle i did win 150 btc from primdice site dice
So you were playing for 5 years on that website and you still misspell its name. Careless mistakes happen right?
Let's start with the start.
Sign a message like "today is 2019-04-30 and I am niceonelok" with a wallet that was holding over 140 BTC anytime in the last 48 hours.Without that you can claim anything you want, but nobody would believe you.
only 140 btc ? what happen to the other 10 btc ? he lost it ? anyway even if he has the exact 150 btc and even if he sign a message with a 150 btc on his wallet . that will still be unbelievable . what if he only borrow that funds to someone else ? or what if the signed message is owned by someone else ? or what if the amount of 150 btc came from other sources and from the gambling site that he mentioned ? there are still so many what if's .
