Hi everyone,
it was indeed long time ago I was active here due to private life.

Anyway, I am surprised that after so long time (since I was active here) there isn't any multisignature platforms out there (except for keeping funds in a wallet).

I would like to know what the main reason is about why multisignature wallets X-of-X isn't used in exchanges or games. I mean by using X-of-X multisig addresses it will greatly reduce the risks of hacking as well as inside jobs in a platform.
Note that I wrote X-of-X because it must be equal, some platforms out there uses X-of-Y multisig wallets but this doesn't give the client/user control of of any transactions made in case of hacks.

Perhaps there are multisig platforms (exchanges, games) out there which I am unaware of, if that is the case please let me know.

Regards Anoxy
