More and more people are opting to open contracts on-chain instead of on exchanges.
In terms of experience, on-chain can already accommodate enormous liquidity and is transparent. Because whether or not a card is 'face up' is the same in CEX; those capable of executing a sniping move can also see.
For large contract positions, the fear is not about whether a card is 'face up' or not, but rather about being subjected to opaque operations or any other uncontrollable situations.
Opening a large contract position requires as much sense of security as possible.
