Problem with X-of-X is that if something happens to one cosigner then the funds in the wallet is gone for good. X-of-Y is the better solutions. And what's wrong with keeping them in a wallet instead of the platform you are seeking?
I get what you mean, but it totally depends on of the multisig platform is implemented. By implementing `OP_CHECKLOCKTIMEVERIFY` we can setup certain conditions to happen, and by that said the funds till be "SAFU".
This means that the regular user in a crypto game platform or crypto exchange would be much more calm in case of hacks, avoding headache and minimizing hacks is really the way to go for all upcoming crypto related projects.
Also a daily trader in an exchange would rather prefer to keep on trading instead withdrawing the funds, and the regular user is naive and keeps their funds and trust in exchanges.
