Whoever created and promoted this encouraged irresponsible gambling It is fun if those involved are friends and the atmosphere is fun and enjoying the conversation, but it's different when there's seriousness in the chat group, fun or not this is not to be taken seriously, we all have to stop gambling at some point and it should be based on your decision alone.
Stopping gambling or continuing should be based on one's decision and not because of the urge of your group or someone who has the authority to tell you to do so, we should decide for ourselves because it's our money and our enjoyment that matters.
