I have never bought weed with my coins, never bought weed period, though it is freely available here.
For my Coins I did not spend any fiat. Did buy me some pizza and whisky with my hard earned coins.

Stepping into an investment a bit too late and ill informed is always a big mistake. You cannot blame bitcoin for that. Bitcoin is not just for investing and HODLing. It is the basis of the cryptocurrency revolution. You have invested in that, you brought change to the world, so be happy with that idea in mind!
