and after use this bulshit in my ledger show transaction whit this TX: 67f67d2e85c9d5d55e9339d8b57c0cd38966572062fbdd295c11e01abf0f4466


so basicly now my old transaction is still stuck in network while they somehow transfered 0.05 btc from my oryginal one into thier wallet I start doubt in blocchain technology if someone can still my money from blocchain unconfirmed transaction just know my TX
