Yes, you can decide to do 1. alone and get the 2.95%. This used to be a nice rate when there was no fiat inflation, it doesn't look so great anymore. So it would be a pity to do 1. alone, a lost opportunity.
But 1. is a bonus, it's inconditional. While getting the interest from 1., and if you have time and feel motivated, you can also do 2. You should normally be able to get another 15 -20% on top of the 2.95% for a total of about 18 - 22%
If you don't have time or don't feel motivated, you can do 3 on top of 1. 3 is of course not as big an earner as 2. but then you don't have to do anything, it's purely passive income. So you can do 1. + 3. and that would get you about 11% sustainable passive income. Sustainable because it's not a reflexive activity like on most other blockchains, it's from a non-financial activities (blogging and curating)
