Wiring more cash is one way to add bitcoin exposure. Borrowing against the bitcoin you already hold is another.
B2X does the second one: your collateral goes into custody, the loan buys an equal amount of bitcoin, and you walk out with roughly double the exposure you walked in with.
That's more bitcoin working for you, and more at stake if the price drops.
