it is time to but BTC and other crypto to rest for awhile as Chinese government are keep on tracking some suspicious ICOs and regulating some BTC exchanges, this is another BTC obituaries. Jamie Dimon was influential but he is not right, the same happen 3 years ago when Mr. Bufett said that BTC was mirage. The gullible guys believed what these 2 brilliant men said but they don't believe the power of bitocin. Resurrect and rejoice when the segwit2x comes this coming October.
The Bitcoin community right now is quite gloomy with all the deluge of so many bad news and rumors of bad news circulating all over the net. But once the smoke gets cleared am sure that Bitcoin would rise again just like the phoenix rising from ashes and these people who are spreading FUD would be signing a different tune.
Bitcoin is not perfect and will never be...there would always be challenges that must surmounted for it to continue on growing and be accepted in the mainstream. What is happening right now will be history next month. After December 2017, we can be able to see a better and more vigorous Bitcoin all fit to meet the challenges thrown its way.
