That sucks man. Can you imagine the heart dropping feeling if you were to click send & see what you’d just done?
i had a very similar heart stopping moment sweeping a paper wallet many years ago. clicked, realized my mistake (failed to sweep all of it.. dont ask and this was before RBF). man till i verified the change went back to the paper wallet addy.. well.. not a good feeling.
TLDR check it several times when messing with stuff.
Yeah, I hear you.
I remember once I was transferring some amount of BTC (double digits) and was waiting for the confirmations. It took a while. Man, that was a long wait. But it went through eventually. It's always gone through. Never lost a sat. The Bitcoin network is a model of robustness. But it won't forgive you if you make a mistake. Which is one of its powers. No safety net. No customer service/bank to call to. WE are the bank, so we'd better give it the respect it demands.
HoDL.
