I tried both and can tell you that dropshipping is nearly impossible. It was possible 6-8years ago but now you can not do it anymore. Nobody wants to wait 6 weeks to get his overpriced, low-quality product... You have to sell something special and know how to invest in ads.
Affiliate Marketing is much better imo but hard to learn.
Learning SEO and Wordpress is a great step since you can do so many things with that.
Dropshipping wasn't that profitable even in old days and depends on many factors.
I thought about a service that can help people buy from alibaba and amazom, if you can limit the service to specific countries where the use of debit/visa cards or PayPal is not allowed by law. Users from those countries need this kind of services if you can prove credible, and they can pay you using btc or any other crypto.
Affiliate Marketing can be also a great source of income, but you have to compete whales in the field .
