Yes, I think he said that in a video I already watched. He discussed how most of the guys who got a 100x or higher was because they couldn't get out of the trade. Kind of a forced HODL, and not unlike Mt. Gox caused forced HODLing of bitcoin.
I'm honestly thinking though that this time around, alt season won't happen nearly as much. I see bitcoin is blowing away most other coins. I'm still sitting on major losses from SOL, about 8k, and ADA, about 2k.. so that really sucks. My life is always being too late. I'm sure if I got in during the summer, when bitcoin was at 30k, vs. in the fall after it was coming down from 69k, I perhaps would have taken a 20 or 30% profit and gotten out. But I started getting into SOL and ADA with barely not a single profit. Just averaged in... and it got lower and lower. Now, I'm just not sure if I should hold any longer. I'd like a $50 SOL, and then maybe get out for a 75% loss which would be almost a relief and then go into bitcoin which I have no trouble holding.
