Re: Ask HN: Why Don't You Accept Bitcoin
#12Two reasons. 1. Price volatility 2. Bitcoin is designed to be deflationary. Most people that buy Bitcoin are letting it sit there and hoping that their investment will go up rather than using it for purchases.
1. that's no issue when you just use Bitpay/Coinbase to exchange the Bitcoins for USD/EUR immediately.
2. first of all, that's not true. More Bitcoins are created every day so it's inflationary, not deflationary. Secondly: that would be a good reason to accept Bitcoin. Who doesn't like getting paid in something that will appreciate in value?
