# Smart contract to buy a service

I want to work on a smart contract that manages monthly subscription purchases on my website.

Is this a valid usecase for smartcontract?

I read a lot of tutorial on smart contract but dont see a way to do that, because I need to link somehow an account on my website to an eth adress (the subscriber).

• Maybe you can but you need to develop a dApp for it... the dApp will be registry the privetkey and who have the token off payment and use it for subscription – TahaBA Jan 10 '18 at 21:04

For example, less than a month ago, I think the price of ether was under $500.00 US. Now it's over$1,100. That's the first problem you'll have to solve if you want to use a smart contract for a monthly subscription.
