While investigating through bitcoin there is no such requirement to find the right time or right place to make the investment. All it needs is the research to find the perfect and the trustworthy investment site, because with several multiplier programs scammers roam around the entire network.
but i think it is too much important that if you are going to investment, then you need to choose to right time for investment. you also need to choose the right place for your investment, because if you will not invest in a right time and right place then you can lose your own money, or will just waste your time.
