I use Jarvis. I also have Peppertype and Word Hero. Jarvis is the best. The rest are just trying to copy what they're doing. Nothing else I've seen comes close to Jarvis in efficiency or quality.
A lot of people complain about the price of Jarvis. But 120 bucks lets you generate 500,000 words. Even if you just manage to create 100,000 words, the value is unbeatable. And if you can't find a way to make money with 100,000 words of content, something is wrong and it needs to be fixed before writing any content.
Not sure about Crypto as a payment method. I've never used Crypto so I don't know.
