Take note also that some traders are taking advantage of this funding rate, and some of them are making money because of the funding rate, I am not sure how they can do it but that is common I can see in some discussions of traders.
Maybe funding arbitrage where you will use more than 1 exchange, where you can open long and short trade positions on separate exchanges while the funding rate is different will make you profit off the funding rate.
You can’t make any money this way. Believe me I tried. What will happen is the funding rate will be near identical on all the exchanges.
Even if it is off by a little, you got basically 4 fees you will need to pay which will clear any profits. You would need to pay fees to open and close the trades twice on both exchanges.
