BTC is full of temptation, the currency is a high-risk investment, it should be treated as such, so no matter what your strategy is, or when you want to invest, you should control the risk.Buy before the bull market in the last quarter of the year.If you believe in bitcoin technology, you can buy at least one bitcoin, and you don't have to worry about your investments.Bitcoin has proven its value and demonstrated its performance over the past few years.To me, BTC is the most trustworthy investment currency.
