I think it's not a big deal for Bitcoin to reach the 20k mark .
Though 2018 has not been the best year for crypto currency so far , but there still time .
It's currently at the 6k mark but apart from that we have the highest reach in the past weeks . So just hold your coins ( if you have any) and wait patiently.
In my own opinion, bitcoins reaching $20k dollars is a big deal because in this way most of the people will be getting rich instantly so invest today while the market price is low.
I also feel the price of bitcoin will pump very high in the future. well, I still save some bitcoin to prepare it. I believe, after this crisis, the price of bitcoin will rise again to be higher, even more than 2017.
