I’ve never had an issue but then again I don’t use it for much more than movies and TV. If sync thing supports qnap I might check it out but I’ve been using sync since it was launched (if not soon after).

Sync by resilio. I use it between my computers and nas and between my computer and my vps and my nas and my vps, I also use it between my work and personal phone.

I would stick with namecheap (for now) and pony up for a multi year registration. If in 5 or 10 years they are jacking the price up then you can use another registrars cheap port option to get a discount. I did this recently between godaddy and namecheap. I had one domain left with godaddy that I have owned for over probably a couple of decades at this point and they were seriously jacking the rate up on me, I ported it to namecheap for a massive discount.

They aren’t looking to host a website. They are looking for domain registrars
