In the crypto world, mistakes often occur, my experience also happened a few months ago when I sent $400 worth of BTC and paid a $200 transaction fee for a total of $600 spent. Yesterday Thursday Nov 23, 2023 in Mempool space on block/0000000000000000000022d1fbfb5ea34357dc2c341b160abdf2e8c5a774f847, I found a Bitcoin sending transaction, amounting to 55 BTC but the sender had to pay a transaction fee of 83 BTC or US$3.15 million. So the total Bitcoin that must be issued is 138 BTC. Initially the sender with the Bitcoin address bc1qn3d7vyks0k3fx38xkxazpep8830ttmydwekrnl, had 139.43 BTC. So as crypto users we have to be careful and check the transaction fees before clicking confirm SEND. Have you ever made a mistake when sending crypto resulting in high transaction costs?
