@cryptosteem. Tell the writer of your article to specify what coins are being accepted by the house sellers. I reckon we should warn them to not accept Ethereum or Ripple as payment hehehe.
Most likely scenario is that a payment processor will be used for the conversion, so there isn't much for the seller(s) to lose here when it comes to depth or volatility. It has been done like this for quite a long period of time now.
Overall, if you have something for sale, and you just want to get fiat, you'll accept any crypto currency that your payment processor accepts. Can't blame people for trying to reach as many rich crypto fanboys at once.
