Trading cryptos is now more easier then ever, so i don't know about that threshold. It's more legitimate and common as well, so you actually feel secure to put your money in. Back in time this was way more uncertain, and people think it was somehow more easier to enter because price was "low". It wasn't. Price has been relative all along, and no one knew it would blow up.

People were selling bitcoin when it was dollars, they were selling when it was 100 and 1000 as well.

Why would anyone think it was easier to enter with same amount of money they are considering putting in now? That's a mystery to me. Also CEXes were way more unreliable with their exit scamming.
