Wrong. Now is the time to either hodl or buy more. Why would you sell at a low? We will be green again soon. Blockchain technology can't be "uninvented".
"Buy when there's blood in the streets, even if the blood is your own."
That is true now is the best time to buy bitcoin and hold for long as a long term investment because the prices is very low compared to last several years and if bitcoin gain in the future the profit margin will be much higher and that is why most individuals who has the ability to afford purchasing bitcoin are buying large amounts for there future and I believe that investments wont be in vain
