I was thinking of maybe starting a service where I'll sell shells loaded with np so it makes attic autobuying easy.

No hassle with transferring the np around and risking your own accounts.

So would anyone buy it?

How much np would you prefer on the shell ideally? 500k? 1m? 2m?

Also I am thinking of doing something similar with shells for normal shop autobuying w/ throw away refresh accounts.
