Sounds like your friend has a nice gig found out! I beg to agree with all your points, the digital platform has been game-changing in economies big and small. Heck, even rural parts of different countries are transitioning to e-payments and even crypto!
I've also found my reigns in my own online hustle. I've been doing something called sales automation for start-ups and small businesses. Basically, it's creating a systemized sales funnel. I mainly target start-ups and small businesses because these are entities that usually lack an organized and automated way of doing marketing and sales as a whole, bigger companies usually have this in place already!
This is a nice breather from my usual day job which, ironically, is a sales representative. Lol!
