The issue here is that yes there was a problem with betcoin.ag once upon a time and nobody disputes that but this person complaints about something once happened and not currently happening as of right now.
So, the question becomes how long will we put the casinos in negative until all that is past and now they are true, now if it happened 10 minutes ago we would still assume that is bad, but we had problems dating as far as 3 years ago, would you still condemn a place for what they did 3 years ago and manage to even re-tribute that positively and improved themselves ? Has there been an issue in the past week for example ?
If a place is bad than yeah we would all put negative trust on them but if a place had an issue back in the day but improved themselves and now better we can't keep a grudge for this long.
Betcoin showed the chat history with the player who is complaining , they clearly kept offering him chips and bonuses and he was satisfied but the moment they decided to not offer him any more chips he started complaining here about something that happened long time ago
the fact that he continued playing with Betcoin clearly shows that he was satisfied with them cause it makes no sense to play with a scam site
there are plenty of alternatives but he simply decided to continue playing with Betcoin , does that make sense ?
