I am prepared for whatever increase since I bought the majority of my coins below the $300 levels. I am securing profits every now and then and enjoy looking at what the price is doing. I can stare at the live charts all day. It's better than television with an ongoing bull run. 150BTC that you have is definitely a great amount to hold, but it would be interesting to know what your average buying price is.
My average buying price is actually like 3 USD per Bitcoin, so I guess I am in a good shape. I was just a guy in school back then and these like 500 USD was all I had to invest. I kick my ass to not worked some shitty jobs to get like 1000-2000 USD more to buy more of
