why didn't i do that? FML I've been doing this all wrong.......
Do you still hodl BTC or was that your stash? you can triple your stash by buying back now, so why not.... you waited before just wait again and try and accumulate more coin while waiting.
this is a summary of what I did
originally I had 1000 BTC (~5000 EUR) , lost half

on the first bubble (260 -> 40) but then I hedl
130k is what I left in for re-investing but I am very bad @ daytrading so now I only have 115k

when I buy, I buy to HODL (with a stoploss of course)

i assume you got 300-500 coins @ cold storage and $ 115 k left in cash ? selling @ 600 ... good job, mate.
