There are so many hypes being created in the market by these big fishes but Bitcoin is still surviving and trading at a very good price. We just need to get together to support Bitcoin bring it to the scope of common people. I think there is nothing to worry about it. Lets take Bitcoin to another level.
They are just doing this as they have seen the potential of Bitcoin in the future and they know that the price of Bitcoin is too high now, so they wanted to bag more, so let's not get manipulated with what they are doing in the crypto space, they are just doing this for their self interest and not for the majority.
