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.
What kind of prediction is this? ... Your thinking is an invitation that actually tends to be a negative invitation, and this isn't good for anyone to follow. For me, 2018 remains the best year for bitcoin because bitcoin won't hit up to $ 2.000 - $ 3.000 this year, I'm very optimistic bitcoin will set its best record again this year.
