From your first post about this user's winning, it is clear that he has withdrew 25+btc with 23+btc profit and balance show 0. It means that he cashed out all his money (profit + deposit).
His latest stats
https://dicecoin.io/user/stats/Aluzon , he is not in 4btc profit but only 2.xxbtc profit.
The main question is how could his withdrawal amount is changed from 25+btc to 4+btc, where is the 20+btc gone since he only made 2btc deposit once.
Aha, thanks for the explanation. Answering right away.
Q: How it happened that Aluzon had 25 BTC withdrawn some time ago, and now his account shows that only 4 BTC was withdrawn?
A: Let me draw a timeline for better understanding:
1) He created the withdrawal request for 25 BTC. It reflected in his profile immediately by showing 25 BTC in "Withdrawals" field.
3) Then he decided to cancel the withdrawal. At that point "Withdrawals" field should be showing 0.
4) Then he played and decided to withdraw 4 BTC, which he did. It made 4 BTC to be displayed in "Withdrawals".
Withdrawals (in a profile) = Pending withdrawals amount + Withdrawn amount.
