I am also factoring in the paypal fees when having to do P2P,
My P2P experience I find it depends on the liquidity in your currency pair.
- If I purchase in South African rands for example the P2P market premiums are crazy (7-50%) based on the size but the fiat rails will be cheap sometimes even free to transfer but because so few traders are doing it so they're no they can charge what they like, the standard premium between lets say a coinbase and a local exchange is already 4% so they likley factoring in that when arbing
- If I want lower premiums I need to get stablecoins, or deal with paypal, skrill, wise
P2P isn't just about the premium on the spot buy I factor in the entire process of getting into BTC
