Now I have only 3.45 bitcoins. It's still very small and I plan to collect a few more coins. I'll just keep them. And the rest - I will spend
You're doing well if you already have 3+some BTC in your possession, and it sounds like you have a good plan laid out for your future within the Bitcoin economy. I wish you good luck with your endeavors.
I have something like 2 BTC owned right now, but it's nothing much and it varies between being in fiat and BTC since I trade on the market alot these days.
