I always found it curious why you did this. I know you bought your eth at around $80 so selling at $1500 was a huge profit, but why only target around $100+ above the previous ath from back in 2018? Why didn't you dca out, ie. layer out, say 25% at $1500, 25% at $2500, etc.?
Everything rose too fast, it was insane, eth did not but altcoins rose too much, so, because altcoins rose too fast a huge crash was imminent, so I sold before that, yea there are phases but insanity goes beyond market phases, crypto is 99% speculation, 1% is error. I bought some altcoins few months ago and sold them when I saw 4 times rise and then all crashed much much lower than what I bought. When on profit, sell, there are levels of greedy, I was not too greedy, yes I was greedy because I got almost 20 times profit and it was enough for me, aiming higher than that is delusion but each to its own.
It is easy to trade the past ...
Do you really think that "layering-out/dcaing-out starting at 1.5k" is "trading the past"?
Back at the start of 2019, looking at what eth did over 2017-2018, were you not possibly thinking: "ok, eth reached 1.4k last time, I expect that it can reach at least 1.5k next bull run", so you end up planning to layer-out starting at 1.5k.
That's not "trading the past", that's just executing a plan you made based on the previous bull run.
In Metroid's case he based his decision mainly on
how eth reached certain price levels (or
how the market in general reached those levels) and not just on the price level itself. When I made my plan back in Jan 2019, I did not consider how the market reached certain price levels and only looked at the price levels (though I was greedier as my layer-out start point was at twice the previous bull run ath). For the next bull run, I'll probably factor in how the price reaches certain levels and not just the actual price level.
