I'm very confident that $400 was the bottom. As you say, historically post crash we seem to trend down towards 2x the pre-crash price.
These are great times to trade. It's low enough that I'm confident that it will recover to a ATH within 8-12 months, which means at least 100% gain in my holdings and it's moving quite a bit that I can try and snipe some additional day trading profit.
If it goes to $200 well I have enough FIAT to snap up a decent chunk of coins but it's simply not happening. $300 is even way too cheap right now.
