I have been putting 10% of my savings in BTC ever since it first hit $40 back in march 2013. Will keep putting 10% in, simple as that. Much better than any IRA or Myra (chuckles welcome). If you try to "game the system" and trade the ups and downs remember you are playing in a field filled with pros who use bot-traders and have insanely high IQ's... if you belong to that club, congratulations. if not, tread carefully imagining you are "What's for dinner" of the veterans.
