News like this can send a lot of people into a frenzy with bad results.
However traders love turmoil in a market because it creates opportunity to make a lot of money. When people panic they take illogical actions, like selling off assets at bargain prices because they fear they will lose too much.
On the other hand, a person who knows what he or she is doing will stay calm, do their research, and and cherry pick the bargains that are out there. If you are one of these types of people you will do well in the cryptocurrency market.
We are still in the early days of cryptocurrency and the blockchain so it is a little Wild Westie at the moment. If you can hold your nerve, do your research, and are brave enough to commit you will more than likely do well.
Remember, volatility creates opportunity, but DO YOUR RESEARCH. Don't rely solely on other people's views and opinions, including mine. Construct your own based on a range of resources.
Learn to surf the crypto wave successfully. Good luck.
