Who pays the funding fee to whom?
Funding fee settlement intervals vary by contract. Some settle every 8 hours, others every 4 hours. Always refer to the contract details for the applicable interval.
When the contract price is higher than the spot price, the funding rate is usually positive, meaning longs pay. This increases the cost of holding long positions and puts downward pressure on the contract price.
By the way: $BTC current price 81636 (24h -0.38%).
Funding fees are also a cost of holding a position, so the longer you hold, the more you need to factor them in.
