For me the best time to invest is when you know or learn the value of bitcoin, when it come to drop and up time to time. Like now btc is up and some theory it become high and high if the month of june.
well it is high time for investing in btc now as more people already witnessed how the price of bitcoin skyrocketed and that gave people a hint of how btc can be very profitable especially in the long run. it would've been best if we've started btc early on but better to start now than never
