Here's a calcuator for bitcoin fees that you could use: https://bitcoinfees.earn.com/ It displays fees depending on how fast you'd like the transaction to confirm based on current fees.
https://blockchain.info/tx/dbb5b7fb0febd5e33928ee7034c661803c326b7648a5cbd9561cd8d908fc6c6c I sent it through blockchain app. My assumption is that, it''s due to hashing power shifted to BCH.
Still transaction shows the unconfirmed yet. I tried to accelerate the transaction but the site is not allowing me do that. Please try to use the bitcoin transaction accelerator available in the online. That will help you to make the transaction much faster to reach the destination wallet.
Because of F**king BCH every bitcoin transaction stucked from the past two or three days.
