I have not looked into crypto stamps in depth, but I think the purpose is just as with traditional stamps the thrill of collecting (if that gives you a thrill)
If you check on ebay the prior cryptostamps have quite some worth so you could consider it as investment.

Hope to see you again soon. Sadly I cann not make it to hivefest.Would have loved to give you two a big hug! Or to hang around upside down :)

I'd have liked to be part of that discussion. I find it very interesting just as important.

I would have liked to listen to your opinion.
All the love fren!
