My worst mistake wasn't shitcoining. Although I did plenty of that the first couple of years.
It wasn't trying to trade and getting rekt (Although that certainly happened).
It was putting my ENTIRE Bitcoin stack split between Celsius and Blockfi and leaving it there for almost a year for the yield.
I was a complete idiot, and the maxis of BT educated me about what and insane and utterly nonsensical risk that was. I was incredibly lucky to have learned that lesson before the yield platforms imploded or I would have lost everything.
Listen to the maxis, they know what dangers lurk out there.
