MicroStrategy's CEO Michael Saylor said in an interview with Yahoo Finance that the Bitcoin strategy is actually very simple. "For the past four years, I have been saying every day to buy Bitcoin, not to sell Bitcoin, and to continue to buy BTC with your idle funds. It will always appreciate against the US dollar." Saylor believes that Bitcoin should be part of a long-term investment portfolio and recommends investing funds that will not be needed for four to ten years in cryptocurrency.
