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.
I have been this situation before when the price of Bitcoin at its peak of $19,800 last December that i keep it holding until it falls down to $17,000. Finally i decided to sell it of that value in which i did not regret it because Bitcoin price dips more at $10,000. Now i believed that it will falls below $6,000 but maybe $5,000 is the lowest level so better to sell it now and buy it again when it will falls to $5,000. Sell high and buy it low is the best strategy while market keeps on fluctuating like this.
