We're doing a guessing game? I like it.
How about: make a guess for the poster you're responding to, who in turn makes a guess about you.
(pointless, I know, but fun
)
Wee, I wanna play. 200 BTC.
You registered this account when price was between $50 and $100. Judging by your first posts however, I get the feeling that's either not your first account on here, or you've been exposed to Bitcoin before registering. If that's the case, all bets are off, depending on whether you seized the very early opportunity or not (no shame if it's the latter -- I'm just mentioning the possibilities).
Because of that uncertainty, to stay within semi-acceptable (to me
) confidence, I'll have to give a pretty wide range. Say: More than 100, less than 5000.
(edit) Your estimate is a bit off, but less than an OOM, so ¯\_(ツ)_/¯
