Yep, I do promotion on my Hive posts on X, Noise.Cash, Bastyon, DeSo, and Tangled. It's quite helpful.
Each level takes progressively longer. Getting to level one takes about a week, level two takes about a month, level 3 takes a few months, on and on. I'm at level 3, and I have about 92 days to go to get to level 4. I don't remember exactly how long getting to level 5 takes. Probably several months, or even close to a year. You can refer or recommend Qortal to people at any time, as that has nothing to do with your level. If you want to be able to sponsor someone so that s/he can start minting/become a minter, yes, you do need to be level 5 to do so. Minting is not required to utilize the many aspects of the Blockchain, but is rather a motivation to keep your node online 24/7. 😁🙏💚✨🤙
