Seems to be wrong because I know for a fact you can get way lower fees by first switching to XLM in coinbase based on multiple other people saying similar. Also, P2P exchanges often do have KYC.
You can convert into altcoin such as XLM to reduce the fees, but if you sell XLM, your profit will not be bigger if you still hold bitcoin, especially if the bitcoin price can increase the price now.
You need to wait for a while to sell XLM until the price can increase to make a big profit, but there is an unknown time for you to wait for the price.
I think the fees are not too high compare to your profit, so I think the fees will be small.
But I wonder how much you want to pay the fees if you're going to search which exchanges can use low fees to withdraw bitcoin to USD.
