More and more people are opening contracts on the blockchain instead of on exchanges. In terms of experience, the blockchain can already handle huge liquidity and is transparent. Because whether it is a clear sign or not is the same in CEX, even those who have the ability to snipe can see it. The risk of a large position in a contract is not whether it is obvious or not, but rather whether it is being manipulated in secret or any other uncontrollable situation. Opening a large contract position requires as much security as possible.
