I have about 150.000-300k I could invest in the BTC, where I could handle the risk. Would you guys do it? Serious answers please since I'm seriously considering. And where would I go on about such a large sum? MtGox? Thanks in advance
If you know you won't panic when the price drops 75%, and can hold on to it until it rebounds, yes by all means.
But if you will keep looking at the graphs and tickers every day ... and drive yourself nuts.... then perhaps not!
