The advice you'll always receive is buy low and sell high, I could be wrong but I feel bitcoin is close to the top with regards to its current price, I expect a fall of some extent in the coming weeks, however it is impossible to predict with anything even close to certainty.
We strongly recommend you if u have already invested then check for the rate, if price increases and u understand u r in profit then hold the profit and withdraw the capital which u invested this helps u a stress relief also u can go with your profit rate increments.
Hope I'm done with my best, hoping u are glad.
alright. but am yet to invest anyway. . . but will keep this strategy in mind for future purpose
