Man, you are impolite!
If you have any question when you visit a VPN service provider, you can always check their Support page.
In this case, if you weren't rude, you would discover that ProtonVPN has Four Payment Options.
These are:

• Credit card
• PayPal
• Bitcoin
• Cash

You have to sign up at first under the Free plan and then upgrade your plan from Dashboard to pay with Bitcoin.

I think it is important to remember that some VPNs offer "privacy", but you will need to trust them to give you said privacy. For example, if a VPN claims to not keep logs, you need to trust they actually don't keep logs.

Also, regarding using a VPN for streaming, many streaming services will block IPs associated with data centers, especially services that offer content based on geo-location. If this is why someone is going to buy a VPN service, it would probably be best to purchase a one-month plan (or the shortest plan available) to make sure they can actually access the streaming service via that VPN.

I use Mullvad and I love it, no complaints here! Connection is always fast and secure

Great idea to make list of VPN providers. But your list is incomplete. There is some popular providers which accept BTC for payment is missing. I can suggest to add few:
ExpressVPN https://www.expressvpn.com/
PureVPN https://www.purevpn.com/order

Agree about NordVPN. I was surprised that it wasn't listed in OP.

Good point, streaming services like Netflix don't like VPN's at all, and they're activelly blocking it. Unfortunately, monthly plans cost very expensive  compared with yearly ones.

Was that an expression of politeness? If yes, then what about making a list of dildo shops? LeGaulois Approved ✔

You are right, companies have to earn trust in this business because promises mean nothing if they aren't backed by the facts. The nature of trust in this business is pretty similar to bitcoin mixers.

Thanks for correction   I'll update that column with: Monthly and Custom.

Yeah, that list is incomplete and I really want to make community based list of VPN service providers. At the moment, this list is created from personal experience with dozens of VPN providers.
I didn't include the Express VPN purposely. They have gone down in quality and I am not a fan of Kape Technologies. If anyone thinks that they are trustworthy, then I am open for discussion, it's very important for us to have a list of privacy-oriented VPNs.

As it was mentioned they do accept bitcoin but I wanted to add that the bitcoin payment is different, it won't show up if you aren't logged in. They basically need you to already have an account with Proton team like the proton email and then you have to log into that account to see the bitcoin payment option in your account. Here is the details: https://protonvpn.com/support/vpn-bitcoin-payments/

According to this article (https://restoreprivacy.com/kape-technologies-owns-expressvpn-cyberghost-pia-zenmate-vpn-review-sites/), Kape now owns all of them. I would recommend you to choose different VPN.

Avoid Kape and avoid every company they own.

Whether or not they were personally responsible for infecting their users with malware and invading their privacy with ad injectors and trackers, or whether they only provided the tools to do so to other individuals, is more or less irrelevant. They were in the business of spying on users, collecting their data, and monetizing it, the exact opposite of what you want from a VPN company. Their CEO even admitted the name change was to distance themselves from their prior activities. They bought VPN review sites and then changed the rankings to promote their own services.

Go and look at the Privacy Policies of some of their other VPNs. They are absolutely atrocious.

CyberGhost - https://www.cyberghostvpn.com/en_US/privacypolicy
When registering they want your name, address, and email address, and will store your IP address alongside that. They then go on to collect all kinds of information, including "data relating to the browser you are using, mobile/desktop device, general properties and metadata, OS version, preferred language, the date and time of your visit, battery charge, screen resolution, Google Advertising ID, Gyro-sensor data, screen size, Connectivity (WLAN), Mobile service provider". Tell me exactly why my VPN provider needs to know how much battery I have left or who my mobile service provider is? And then of course, "we may communicate your Personal Data to a member of our group of companies (this means our subsidiaries, our ultimate holding company, KAPE TECHNOLOGIES PLC, and all its subsidiaries)" and "with 3rd part suppliers for the purposes of optimization of our Website and Services as well customer analytics and fraud prevention (e.g.VWO, Appsflyer, Google etc)." Because you definitely want your VPN provider sharing your information with Google of all companies for the sake of "customer analysis".

ZenMate's looks pretty much the same, except they also use tracking pixels, with the data again being handed over to Google for "customer analysis".

PIA is the same. "We may disclose collected Personal Data to necessary members in our group of companies (across our ultimate holding company and all its subsidiaries)".

Remember that Kape's subsidiaries include companies like https://www.webselenese.com, which is designed to "Connect consumers with brands". In other words, a marketing agency. Who has access to all your VPN data, if they want it.

We are not exactly starved for choice when it comes to VPN providers. When there are dozens of better ones out there, why would anyone ever settle for one of the worst?

Avoid Kape.

Https says nothing about the authenticity of the person, website, or software you are dealing with. You should use https everywhere as it encrypts your data and protects against man in the middle attacks and protects against your communications being spied upon. Be aware, though, that that is all it does. It doesn't matter if your communication channel with a scam website is encrypted with https - you are still connecting to a scam website, and you can still download malicious software over the https connection.

Making sure you only download software from the official website or github repository is pretty basic stuff. When possible, you should also verify your download against the PGP keys of the developers or against provided hashes. Unfortunately this is not possible with NordVPN as it is with some other VPNs.
