bitcoin go up over 8k today after went down deeply 6k just few day ago, very good new. Is it a right time for us to invest bitcoin and wait 2,3 months when its price go up stronger. Pls share your thought. I really need some good advice 
You don't wait bitcoin price when you want buy. Bitcoin price increase and decrease every day and it price highly increase after a day. If you have extra money you buy btc and hold it long time.
