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
years from now you will look back at this post with your last remaining Bitcoin worth $1 million+ and you'll wonder why the hell you sold them all away for ridiculousness lol.
