I am not a trader, I don't want to be a trader, I don't even want to play one on TV.
I know a trader fairly well. He trades crypto and fiat. His margins are so incredibly thin most times that I can't even fathom it.
I'm much more a plodder and builder. It suits me.
I think I would have a heart attack trading on thin margins - or at least an asthma attack...
I don't think there are enough anti-acids for me :)
