Personally, I learned about BTC a year ago and started mining with a small $200 purchase of GPUs.  I mostly read posts and seldom posted.  Then I just got busy and stopped following it for a while (I even switched from pool mining to solo mining so I wouldn't have to deal with pools shutting down or needing miner upgrades).  I forgot about it until one day when I needed to reboot a computer and saw I had found a block solo mining.  I decided to look into BTC again, and saw that ASICs were being developed.

So I looked into it a bit, pre-ordered one, and have mostly been reading posts and seldom posting.
