Collapse of the bitcoin

First I apologize for weakening my English.

After the huge rise in the price of the bitcoin against the dollar since its launched and its high prices these days with all the unprecedented I think that's the bitcoin will begin to decline starting from the next year, and this may lead to a collapse of the currency price, and for a number of reasons.

1/lack of confidence of governments in this currency and there's no desire to deal with it.

2/The desire of some countries to launch their own currencies as in Dubai, which will launch its work from the beginning of next year.

1. The rise and growth of the Chinese economy and China's desire to have its currency as a hub for global transactions.

2. Currency link with money laundering and weak ability to control this big stack.

There is a talk that China is launching a new digital currency.

As a combined reason, I think the bitcoin will see a major breakdown in the next year, what are your opinions?
