Maybe... I was too busy and only have few hours a day to spend in collecting bitcoin and sometimes even if I have time, I'm just too tired, that's why I am saying that maybe my life has changed a bit.. Before I am not interested in any talk about internet and this currency, but now, I am always reading news about it.
I think no, not yet, wait a little more...The price is still increasing and probably we will reach $500 by July, so don't sell yet if you are not in need of money..
As of this time, I am into saving my money than investing it in business.. I have no idea on what business to engaged into..Usually I save atleast a few dollars every end of the month...
I too is been looking for ways to earn bitcoin, but I figured out that in bitcointalk there is signature campaign, but it won't be profitable if I am in a lower rank,,
I am still thinking where to use my bitcoin, usually I use it to top up my mobile load..I might find new uses for my bitcoin when the exchange where I keep my bitcoin would offer something new..
