Just jump in and don't worry!
Now,i think the right time to buy bitcoin. Because now bitcoin is worth $ 8k. But on December 16, the price of bitcoin went up to $ 18k. So I think if you buy bitcoin then you can sell it for more than $ 30k at the end of 2018.
I wanna know how you can make that prediction like this, you may want to share how you predict it, or maybe you have information that us don't know but you know it. please share to take profit together.
