I am very disappointed to see the price of bitcoin destroyed in recent days, I have lost a lot when I bought bitcoin at a high price, until when this bitcoin price dropped.
At what price did you bought your coins? There are immense reasons behind the price drop of bitcoins but none of them is reliable. Bear markets will end soon bringing bull run. HODL and you will see some good profit for the number of coins you will own. Instead of selling at a comparatively lower price, why don't you just afford holding them? If it becomes partly riskier for you, than try to set a stop loss which can be affordable and buyback some coins once the price drops below your stop loss.
Also i guess, bitcoins might soon see a amazing price as the markets are slowly turning green which is a good sign of growth.
Don't get your hopes too high. The price may stick to $3-$4k for quite a long time maybe more than a year. Remember that it took a year long of bear so its going to be a bad years ahead if you expect $20k. Its going to be difficult to convince an investor to put money on bitcoin if they see the charts.
