I believe that now is the right time to invest into bitcoins as most probably the price is going to rise because of various reasons such as block increase and halving.
I think we do not know when the price will go up? because it depends on the user's demand in bitcoin. we can only predict price and hope we are right. but now the price has decreased. usually after the price fall and prices will rise. so I think before the pump price. you should collect and buy bitcoin
