Usually online merchant which do Digital trade only will use bitcoin , if i am selling cloth i will be taking cash
Why? Once the bitcoin payment has confirmed it can't be reversed. Shouldn't take long to get one confirm.
If you're selling a $10k dress for the Oscars, maybe you want to wait a few more minutes for a couple more confirms.
Example 10k USD is 10k USD , if you exchange to bitcoin its so much less than 10k .
