Bitvest has still the good reputation and it is still a creditable casino to play with. However if anyone feel their withdrawals may be stuck or pending, they can always have the choice to skip the casino and play at another site.
Bitvest used to be a reputable casino. But due to some issues and lack of communication of the owner, it affected his business and gamblers started to have doubt if they will continue to play on the site.
Back to the problems/issues of Op that he/she mistakenly send his/her LTC to BTC wallets and asking for justice which is this issues made by his careless thinking. But I don't know if there's a chance that Op will have his/her money back cause this is not about the casino's mistake but Op's mistake.
Yes its his fault but he is hoping Bitvest casino will somehow help him if he can still recover the funds. Unfortunately there's no good news for him.
