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 
I think you should not be much concern whether it will dump again hardly. Bitcoin's price today is way too far from its stable price before, about 19k USD so that don't make it a big deal if you tend to invest today or buy some Bitcoin today and it will dump several days after. Justin be contented to its drop today because it did enough to somehow satisfies us.
