How many exchanges you know of that have too high withdrawal fee? I was shocked that Dcoin exchange wants 0.001 for any bitcoin withdrawal you want to make while other exchanges charges only 5000 Satoshi for bitcoin withdrawal, I was forces to exchange my bitcoin for litecoin before getting my coins out
As a reply above was right if you wanted to withdraw this for the safest way you can withdraw using switching into other coins like Ethereum that has a very low fee. And then, once you have been transferred to the exchange that you desire to use because of low fees will be fine.
Try to research because there are many websites that tell of comparison between those crypto exchanges.
Just like this if you want a reference,
