Hello guys I've used bitcoinvanitygen address and linked it to blockchain, I always thought it was legit as I forgot about those private they thing, i thought they were legit enough I made a wallet and used it on my main, I was receiving some small $50 -$230 bitcoins and got them cashed out no problem, until like 3 months came and I got 1.2 received on my wallet, an hour after a $200 payment was sent to me I saw a unauthorized transaction with 1.2 bitcoin sent to a completely new address, I was feeling shit and dismayed as the money on my wallet is really needed in real life, now I'm broke here is the blockchain link "
