Ironically I think this is a great move.
People will start interesting more in cryptocurrencies, and both the users will
become more anonymous and VPN providers will enjoy less painful payment
proccess, without fraud and chargebacks and crazy fees.
PayPal is a huge rip-off, charging 4% just to move a number in their database
is insane, back in the 90s it was acceptable but definitely not today.
Providers who fail to implement cryptocurrency support should either start
doing so or fade away.
I'll be the first to admit I'm not all that versed in cryptocurrencies, but I have started reading bits and pieces mainly after seeing the various articles about PayPal cutting off unotelly (a DNS service provider that gets people past geolocks). Accepting bitcoin is wonderful and all, but eventually you (meaning Air or any business with expenses to pay) need to convert those bitcoins into dollars or Euros or whatever it is you need to pay your bills with. Isn't there the same risk when Air tries to convert those bitcoins into Euros? I imagine some of their expenses can be paid with bitcoin, but definitely not everything. Isn't there some kind of risk exchanges (or whatever you use to exchange bitcoins for cash) will also cut off access to services that governments deem "inappropriate"?
Again, I admit I know very little in this domain, which is one of the reasons I've never dealt with bitcoin ever. With no knowledge at all about how it works, etc., I've just stayed away fearing that I might have a digital wallet full of bitcoins and no way to exchange them -- because my bank doesn't take bitcoins for my mortgage, the hydro, natural gas nor water utilities take them, etc.
As great as bitcoin is there is limits with it, for example some countries don't actually have any way to exchange them, and most that wanna remain anonymous ain't exactly jumping at the opportunity to put their credit card info into a site they don't know much about to exchange their money for bitcoin.
