In the first place bitcoin has his ability to come up from the huge downfall, so we all knew that if we invest in bitcoin we had a bright future for this tokens so i myself would not hesitate to invest this coin..
Up and down are the part of the btc and due to volatility is is famous and everyone knows about it. We have seen the rise of 18k and also the fall to 6k which happened last month as well. But those who are fearful should be cautious and stay away from this market if someone is not able to take risk or do not want to take risk.
