@Selina M, be careful with the media / news about the prediction of Bitcoin, there are dozens of sources that predict Bitcoin right now.

Bitcoin prices are largely determined by: buyers and sellers, to determine the up & down, the more people buy the higher the price, What's the difference, now & in 2021, or maybe down (people from outer space) to buy all the Bitcoin, so that it can reach $100,000.

@Selina M, for now Bitcoin is still very good to be traded and invested, why should you wait for a certain year, now it's a good step if you know it.
