Best website to sell PDFs/ebooks?

I didnt know in which section to post this so sorry in advance .

I have an idea which involves selling a pdf book i wrote myself , what is the best way to sell it ?
Ideally i would need a website that allows me to:
-Have a low or non existent cost per month or fee per sale.
-Automatically send the book to the buyer.
-Get paid in crypto rather than paypal or credit card .

Do you guys have any ideas?
Im currently looking at these:
Shopify , https://sellfy.com/,https://www.bigcartel.com/, https://getdpd.com/ , https://www.fetchapp.com/ , https://simplegoods.co/

Try sellix and nowpayments.

I have the same question. But the other doubt is try find a good website to sell ebooks in general and make money methods similar to hackforums or any website with marketplace section included.
Anyone know any hackforums alternative websites?

maybe try through facebook groups

I love Gumroad. It has loads of built in functions including an emailing platform that you can use to message your customers. Great for setting up lead magnets to build a mailing list.

Amazon kindle if you have the knack of it.
