...I don't trust the prices in the pre-market, because usually the prices there are far away when they are listed in the spot or futures. Once I tried that, I observed that most of them are also expensive in the pre-market then once they are listed in the spot, their price immediately drops.
Nevertheless, the premarket is a good tool to fix the price if it suits you. I used the premarket on Bybit and KuCoin several times to sell coins that I was supposed to receive as a reward for the testnet, and I was pleased with the result.
