I bought 100 coins at around 13$. I sold 65 of them for BFL pre-order (that was 1333$ at the time)
. I bought approx 45 at around 45$, just before exponential growth.
Sold 20 BTC at 110$ to recover my last 2000$ I put in (not bad, considering that it more than doubled). Just sold 60 at 132$.
So, total investment 3300$. Total return, approx 10000$.
Take from that maybe 600~700$ I invested in mining hardware... Custom FPGA hardware array, running at 2.2GH/s total @ 450W. The FPGA did not cost me anything, they are telecom cards we have at our job that don't sell
. I adapted them, reverse engineered (easy since we made those, and have all the hardware specs), designed backplane PCB, PC interface, custom PC miner software interface, etc. So, there's a lot of fun involved in the process too
Mined about 20 BTC since January.
Of course, gained and lost a few BTC betting on the exchanges, trading LTC, BTC, PPC, etc. So I learned there too!
I still have that last 60BTC worth in fiat at the exchange, in case there's a weekend dip
But for now, it's way too volatile to risk it. It may raise to 150~160, sure, but what the heck... I made a lot in a few month and more than happy
And of course, some penny change BTC (2 or 3), plus my mining hardware that still run 24/24 popping .16BTC/day (that's still ~20$/day), although I now mine PPC which is worth 2~3 times more at the moment.
And... I'm waiting for the correction now! Well, if it happen
