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.
Yes, in BTC no automatic transaction but i believe more merchant will accept BTC. More confirm for more secure transaction.
