And yes, it finally started, from now Bitcoin will start going down, it will not be as 2018 but we will see a downtrend in the next 3 months, if you already made money is time to sell.
I will celebrate it by buying more bitcoin but I will buy it step by step because I think the price will vary to make me get bitcoin at any low price. Besides the downtrend, I think the price will still go up, but I will use it to buy back if the price goes down again. Maybe it is time that the buy low and sell high strategy can be used.
