Hi, it is looking quite OK. Wish you all the luck possible with this project.
My few cents on the matter:
Improve you Facebook page with more info on what you are offering, upload some nice graphics for header etc.
Promote your shop there with fun giveaways rather than affiliate programs.
-finding more cool products
Definitely yes, as much as possible, go crazy with it!
-enabling more crypto coins available for payments
Don't go to crazy with this one
i would say max 5-6 most popular crypto.
There is a reason why shops only use few card processors, to much options causes management chaos
and somehow scares people off
-affiliate program
I was never a fan of that... may turn in to click-baiting annoyance.
Active for limited time as promotional purpose? Than maybe.
