I consider 400k impossible (virtually). To good to be true. I would be really happy reaching 50k in two years (max time I plan on holding btc), and would conform even with 20k. 100k would be a dream, but I know deep inside that I would shit on my pants everyday at night if I dont sell at 60k or 70k or whatever, so doesn't matter.

I am used to traditional investments and there's something inside me yelling "stupid dreameeeer" every time I consider respectably probable getting an interest of 100% or more from an investment in just a couple of years.
