I'm a novelist, I'm not popular but I do have Patreon. I started September 2019 and as of now, I have 64 Patrons. Patreon is really good to earn extra income and a way for fans to support their favorite creators. If you have a number of audience, I think you really should start Patreon soon. 
Based on my experience, I think you should start with 2-3 tiers and $2 being the lowest amount and the $5-$10 the highest for now because Patrons like having choices. Even if a certain tier doesn't have a patron yet, don't be discouraged because there will be someone someday that will want that.
Also, if you put the price into $1 you'll never be able to change that if it started getting patrons on that tier so you should set the price based on the privilege's worth patrons will get. Not over priced but also not below its worth.
Also, it's good to have schedules when to update and how many you will update in a month so Patrons will know what they will get with their money's worth.
Anyway, this is just my amateur advice on Patreon. I'm no way expert on it but from my experience, I wished this was what I did when I first started. 
I hope this helped and goodluck with your future patreon page.
Ps. I'm sorry for my bad English. Not really good with it.
