I'm kind of in the boat same now. I've got ~260 days left on my current account so I'll be able to get a bit of use out of it. But I am extremely worried about how I will renew my VPN service with Air while staying truly anonymous.
The last time I bought a plan, I even did it from a VPN IP, and just used a prepaid VISA. Even though we're well past that law enactment date I previously had not had problems just a few months ago.
Paypal is not an option anymore I guess, unless Air can arrange a US transaction node for US customers (i.e just as a test I bought a CS token through a reseller that went through fine).
I'd really hate to go back to CS too because their servers are inconsistent and they have way less.
It's not even about who I am, or what I am doing online. It is about privacy and free speech plain and simple. I do not need the hassle of the thought police bothering me for something I may have said online, especially in today's rampant anti-free speech culture in the US, UK and other places.
I am less than impressed with BTC options as for example anything looking remotely credible wants you to verify your identity in some form (phone, documents, SSN, etc).
Sure walking into a store and buying a prepaid has risk, but you can greatly mitigate that risk by walking to the location from a distance of several miles, and all the other usual dress-down stuff.
Cryptocurrency is great if you want some measure of anonymity, but unless you are selling a service you can make money from it seems the barrier to entry IS your anonymity
