I will eliminate the "or" and write on both. Let me start with your second question. I stumbled on this forum by chance. That was how I "detected it". I was ferociously looking for sites that could teach me what Bitcoin was all about and that was in 2017. My search on Google brought me to this forum. I observed it awhile and in less than two weeks I made my conclusion and registered on it.

My decision to remain active here, besides the monetary gain, is simply because there are loads of insights on knowledge one gets for free here. Most crypto fora are full of spam and shitposts. It's discouraging posting there, to say the least. I had accounts in a few of them but I stopped posting there after awhile. There was one – Moonforum (or so) – that would've served as a strong competition for Bitcointalk. Sadly, that forum didn't last before it went under and shutdown.
