50$ of transaction fee? At current price that means 0.075 btc per tx. I can assure you that you can mv btc from one address to another for a lot less. Even without paying any fee at all. It all depends on how "old" are the btc you're moving, the amount of btc , the number of addresses involved in the tx and if you're in a hurry or not.
