A one-page site, a marketplace, or a full-fledged niche store on Shopify through dropshipping?

Question

Electronic commerce

Hello, I want to try my hand at dropshipping. Now I'm dealing with this.

Do you have a question about which platform will be easiest to start with? For Amazon, I understand that if registration passes, or you buy it, you will need to deliver goods to Amazon warehouses and for this you need some kind of cash to start about 2k $ + -. I'm a crest, I'll register a stick and transfer it to a business account from Poland, is that normal?

eBay seems to be the easiest thing to do, right? On registration that everything was ok only.

And there is still a question with one-page sites or full-fledged stores through shopify. Now I’m delving into targeting, I’m studying Facebook blueprint and other resources on setting up and working in a drop. Interested in whether what will happen, either a one-page site with one product or a niche store, affects Facebook ad bans?

What will be easier at the start or how to start and where to try to go?

Yes, and the question is one more question) I was a poppy, but in the cycle of events I sold my poppy) and studying the drop I see that there are a lot of apk on shopify only for poppy, if you use shopify, is it better to take a poppy again? And for the rest, a desktop PC is suitable for starting? I will be grateful to everyone for the answers and comments who will share their experience.

And advise a clean budget for starting target advertising when there is a working tool and paypal. And that Paypal will hold my money when selling goods and entering funds into the account, and in this case, you still need money for a while to buy goods from my card or on the same stick? Should I stock up on this? And what is the duration of the hold? Or will they not?
