One of the best features on Stake is the public chat rooms. To gain access to this feature, all players must pass a wager requirement of $500 USD.
Here are some important chat rules to follow:
Don't spam, harass or be offensive to other users.
Don't share personal info of other players.
No alts in chat are allowed.
Avoid using CAPS since they clutter the chat.
Don't beg or ask for loans, rains from rain-bot, tips or doubling coins.
Don't use URL shortening services.
Use the designated language channels accordingly.
