I just wondering , how can this type of mistake possible? I think fee are automatically being charged right. This is such huge huge mistake ever , I can't even imagine if that was me. Pheww. Looking at current btc price and 15 btc as fee. I'm going to shop and buy myself a rope. LoL !
The fee is whatever is left from the inputs that is not spent. If you are using some a wallet this shouldn't happen unless there is a bug.
That what I thought , I've faced this kind of problem but not bug. There Android wallet where u can enter your own amount of fees by your own desire. So it's all manual not auto like these days. This 15 btc fee happen long time ago. Maybe 2-3 years ago if I'm not mistaken. Well sorry to hear his biggest mistake ever. Now when he look back at his mistake , I bet he can't really sleep well hehehe 😂😂
