I have experienced in crypto industry from the last five years that crypto currency market take bullish turn in the end of year so I am expecting something positive with Bitcoin I think btc may touch $30000 mark if market could able to keep its momentum nevertheless it's hardly to predict which altcoin will rise higher because there are lot of good altcoins which will definitely give tough competition to each other.
I'm always optimistic about bitcoin even though today bitcoin is experiencing a very hot turbulence. It is true that it is difficult to determine and predict which coins will experience a high increase at the end of this year. Today is the day when we see difficulties in the market, especially with the drama that has occurred recently from people who can be influential in the cryptocurrency world.

If you look at the annual cycle, it is true that the market will recover at the end of the year, but of course that will not always happen, it could be that this year the market is not doing its usual. Now with the situation like this it is easy for FUD to enter and that is something that makes it difficult for the market to recover.
