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 !
Fees can be set manually if you desire that way you can decide if you want to add a big fee to get a very fast confirmation, or you can send a low fee if time is not really important, I think it was a mistake of someone who was new to sending bitcoins, that is why, even if you have lots of bitcoins you need to send a very low transaction first as a test.
That what I thought, maybe he little bit confused with the fee and the total amount he/she supposed to send. Or maybe he/she not really good at English. This person actually from China of I'm not mistaken. I've watched someone from YouTube talk about this huge mistake ever in Bitcoin fee transaction LOL. 😆
