what i do not understand is this. lets say i have $200 in my wallet on blockchain.info, then i send $100 to someone, even if its unconfirmed or low fee i am sure
the money $100 will be deducted from my account. How is it possible i could spend a money that already deduct from my account and move it to another wallet..
i wish to see a video demonstration of this. This is very very interesting. very smart trick.
On blockchain.info's wallet this isn't possible since there's no way to perform a RBF but on other wallets like Electrum you can easily do it yourself.
Here's a
step by step guide if you want a bit of explanation on how it happened.
