It's easy to look at BTC in hindsight going up 10x or 50x or whatever and think you should have just gone all in.
In reality, at the time it was hard to believe BTC was going to still be the best with everything else. I messed with ETH, alts, ICOs, shitcoins, etc. ICX fucked me up.
Riding a crypto portfolio up to 700k, then back down to 35k, it's hard to justify throwing more money into it, no matter where it is.
When you're up you think
shit I'm already overallocated in this asset class, why would I put more into it?
When you're down you think
shit it's gone so far down, will it ever recover? Am I just throwing good money after bad
Then you think about how you have 50k RRSP contribution room and 40k TFSA room that you haven't used, and you only really have 10-15k/year you can set aside for investments, so you fall for the diversification meme and try to max those out instead of all-in BTC since hey if BTC does ever go to 0 or replaced you don't want to be completely fucked.
Anyway, that's my cope and I'm sticking to it.
