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.
Yes, This year it might be not possible for Bitcoin to cross the value of 20000$ in the market, instead of panic it is better to hold them until the market starts recovering. You can see from many the price of Bitcoin constant at 6000$ which is very good sign for people who are holding.
