If bitcoin transaction fee is 0.5$ then you can do bitcoin transaction. Because Bitcoin transaction fees usually range from 0.1$-100$.
I am not sure it has ever been $100 in history.

I don't make screenshot and attach images here as images might have problems in future. You can click on links, choose all time tab and check it by yourself.
