I thought there were two groups that could reference each other. Actually, I was wrong; it's not about having more groups, but about having quality ones.

Last night, the boss shouted

'空以太' (short Ethereum), he shouted in the group to go long around 4560, and to add positions at 4500, it was really fatal! $ETH
