I think bitcoin could well reach $2,000 - $3,000 if this $6,000 support get's broken. If you would sell now chances are high you could buy back and thus double your btc holding.
This is not financial advice, just a thought.
And this is not a good year for crypto I believe. Late 2019 we'll see some action.
If you wanted to sell then you should have sold a long time ago, this is not the moment to sell, you are only going to lose money that you could easily recover in just a few years if you were patient enough to keep holding your coins during all that time.
You sell if you believe that price will go down, you trade like that. You can believe in great future, but that's holding if you have plans for future. What you can do now is to make some profit in bitcoins or cash, you do that by making trades in good time, if you think price will go down you sell, if you think it will go higher you buy. What will happen, nobody knows, that's why trading is like gambling, if you don't try it you will not make profit.
This is a year full with action, of course people wish to see rise, huge rise, that's the most interesting part, that's the action that masses wish to see. Don't be like others, have some attitude, try to not be like most others that only wait for rise to sell and earn cash, use bitcoins and support bitcoins, it's not all about the price.
