Well, China banned cryptocurrencies and that hasn't stopped anyone there, so I doubt it will have much of an effect anywhere else.

The lack investor protection hinders the approval of Bitcoin exchange-traded funds (ETFs) the Securities and Exchange Commission (SEC) chairman Jay Clayton.

The main concern for Chairaman Claiton remains the fact that cryptocurrencies can still be too easily stolen or manipulated on the so called crypto exchanges. The remarks were made at the Consensus Invest Conference in Manhattan, New York. He added that the problem has to be resolved before SEC would make any move to allow the first Bitcoin ETFs.

“What investors expect is that trading in the commodity that underlies that ETF makes sense and is free from the risk of manipulation,” Clayton said, adding that such “kinds of safeguards do not exist currently in all of the exchange venues where digital currencies trade… It’s an issue that needs to be addressed before I would be comfortable.”

Stock exchanges like the New York Stock Exchange have surveillance systems, designed to prevent and investigate any abusive and manipulative activity.

In the recent months SEC rejected a couple off applications for Bitcoin-based ETFs on the ground that there is still a significant risk of market manipulation.

Hopefully this was the end of the depreciation and we'll see a new rally next week. We'll see.

It hasn't broken out below the last low yet, so the depreciation has not continued, but at this point I am not holding my hopes up.

It looks that way for now, but I think only time will tell. I certainly hope that was the end of the depreciation.

Did they actually manage to steal anything or was the hack stopped in its tracks?

It won't be game over until people quit mining and trading it altogether, and I don't think that will happen anytime soon.
