As long as the network is still secure and I keep seeing the massive effort being put into developing bitcoin, buying bitcoins for pennies is great sale! I'm not sticking with bitcoin because of what its doing today, I'm sticking with bitcoin because of the long term potential I see in it.
I know it has been said before but this is a great project and it is always good to see others are as committed as oneself. There is great potential in Bitcoin and working on a project with so many talented people who have a vision is truly amazing.
I do not condemn anybody who is just here for a quick buck because IMHO that's one of the beauties of Bitcoin: it works successfully even if most people don't care about the system and only use it based on rational profit-driven thought.
