Bitcoin is and always will be very volatile, but this does not mean having to give up his purchase. If you look at the chart of growth rates you will see that every year the price of bitcoin is increasing. This trend will persist for a very long time so you can buy it at any time.
I agree. At the very first place, as you enter bitcoin you are already risking the chance to earn. We all know that the value of it is changing and most of the time, the chages that are occuring gives us better outcome. You should still buy bitcoin even you're seeing the price rising because even though the value is already high, there are still a lot of possibilities that it will increase more and will surely benefit you for the greater good.
