Bitcoin fell to 3k few days ago and now we have it again in the four thousand dollars range. It was a sudden surprise and people rushed to invest. There is already a profit of more than 1k dollars for those people. So I think despite thinking over the price fluctuations, you should look for more capital to invest.
It did, but it didn't sit there for a long time to set a record low of $2,800. Those who bought when it dipped to $2,800, congratulations you just made 32% profits and if you hodl a little bit longer and sold before Christmas when BTC reached $4,100 then you are in luck. Timing is very important in trading, regardless if its a bear or bull market.
