Look at this
Transaction[1]. It paid 15x more than it was necessary to get confirmation. It paid $38.77 in fees for transaction that worth $180. If you have a look at old transactions of this wallet, it was always paying optimal fees.
I don't really know what happened there, while it paid 5x more than recommended, actually $10.56 was spent in fees while transacted amount was $1.41, check:
Transaction[2]And here -
Transaction[3], someone even paid 56x more.
Is this done on purpose by some miners to increase the overall transaction fees and collect more fees?
Edit: I had to open this thread on Bitcoin Technical Support board, sorry

This is the first time I've seen that the transaction fee using bitcoin is high around the 38.88$ charge. It's really quite majestic. How did this happen?
I remembered, on an exchange platform when I was supposed to make a transaction withdrawal in Bitcoin, I noticed that the fee was high, although it is not like this 38$ which is really expensive, it seems to be around 5-6$ if I'm not mistaken, but when I checked with another exchange, their fee was around 3$.
But here it is different? Couldn't it also use an exchange so the transaction fee is a bit expensive?
