> forget about the ruthless of business

Noone has forgot a thing just aren't clowns like you who think businesses are some substitute god who can't be beat. Fidelity doesn't "hold" the transactions. Transactions to be relevant MUST be broadcast to the network and if this doesn't happen then the blockchain plods along as if they didn't happen.

Honestly, learn a bit more about how this stuff actually works before commenting.
