I don't get it about PERP Futures
For example BTCPERP funding rate 0.12% (binance)

Reading for binance explanation binance won't take any fee. And if the funding rate is positive LONG pays to the SHORT funding rate. There is said it depends about markets, but as i see all funding rates are positive

So 0.12*3*365days=131,4% like more APY

I can easly go long spot long 1BTC and short 1BTCPERP and collecting funding rate with ridiculously high rate. Where is catch, i do not get it?
