Risky.
You seem to be a really smart guy.
I don't like the fact you donated to something that could essentially be absolute vapour.
You are encouraging certain individuals to attempt something similar to what OP *might* be doing by your behaviour.
It's your behaviour and your donation, but it affects the whole community because people will now know they can get free money by just creating a fake ANN (not saying this pre-ANN is fake, I am saying that OP got money only based on a pre-ANN with no code to show, which sets a dangerous precedent imo).
Sometimes you lose, sometimes you win. I have donated a lot of to crypto projects over the years. Below the line there is a big plus in the balance and brought me of being a very early investor of two top ten crypto projects. Every donation comes along with some risk.
