Recently, the funding rate has been extremely volatile, and people in the group have started shouting "Quick, become the counterparty to collect rent."

Honestly, I also feel tempted, but most of the time I choose to hide from the fluctuations...
Extreme rates = extreme emotions, extreme emotions = you think you're exploiting others, but actually you're fueling the volatility.
If you really want to be the counterparty, that's fine too. I usually only take small positions to test the waters, set an acceptable stop loss, and don't hold on stubbornly until I think "How did I become liquidity again?"
By the way, hardware wallets have been out of stock these days, phishing links are everywhere.
The more volatile the market, the easier it is to get nervous and make mistakes.
Let's focus on keeping our safety first.
Talk again next time.
