Golden Finance reported that Michael Saylor, executive chairman of MicroStrategy, said in an interview with Yahoo Finance that Bitcoin strategy is actually very simple. “In the past four years, I have been saying every day to buy Bitcoin, don’t sell Bitcoin, just use your idle money. Funds continue to buy BTC and it will always appreciate against the US dollar.” Michael Saylor believes that Bitcoin should be part of a long-term investment portfolio, recommending that funds that are not needed for four to ten years be invested in the cryptocurrency.
