It would reach up to $20,000 by the end of this year. however, if something goes wrong the price would dramatically subside like what we have seen last December 2017. you should not jump off and sell your house to invest in this green market because the price is still volatile and no one really knows when the price will fall again like last time.
It depends. There's just so much difference in 2017 and 2020 since 2020 was the year where businesses are starting to recognize and implementing Bitcoin. 2017 was the year of the hype (remember ICO and Bitconnect?) and doesn't really have that strong support which is why Bitcoin dump so hard. 2020 is the year where people see the value of cryptocurrency. Paypal and other many institution is starting to make a move.
