yes the price is change every second up/down so if want to join just do it if don't wast your time
Yes cause the value is very unpredictable you don't know when it ups or down. So if you want to join in invest in bitcoin do it now until the value is dip, buy now and hold it and wait for the right time to sell it. So if you want to earn more profit start now to invest and don't missed the opportunity to become successful.
I agree that now is the right time to buy, the price of bitcoin looks very cheap and early last month everyone hoped that it could buy for $ 6200, and now we get it so buying immediately is the right decision.
