Got some free DOT - yay or nay?

Hi everyone,

I recently received some free DOT from the Revolut learn and earn program and I'm wondering if it's worth keeping and maybe buying some more or if I should just sell it for beer money.

(Just to note: I don't purchase crypto through Revolut but free crypto is free crypto).

Basically I was wondering if those of you who have interacted with the ecosystem could please share your experiences, both good and bad, and maybe give me your overall feeling towards the project?

I currently only DCA small amounts onto BTC, ETH and ATOM which in pretty happy with but I'm open to new experiences (I'm still fairly new I to crypto having started early last year).

Reading through the project website was kind of helpful but you have to take everything with a grain of salt since everyone claims to have the next biggest project.

If I understood correctly it seems like you need a minimum of 10 DOT to be able to stake and even then rewards are not guaranteed which seems a bit strange on the surface but I suppose there's a reason for that?

Anyway, thanks in advance to anyone who bothered to read all of this and can offer me any information. It's very much appreciated.
