It is predicted that by January the price of BTC could rise much more, so is it not cheap to buy now? Maybe, it's a risk that few of us take.
Investing in bitcoin with the idea of what people think or what people predict the price of bitcoin will be in a given period of time is not good, so that if it fails to achieve that predicted price, you will not get angry and be forced to sell your bitcoin at a loss just because it is not what you were told that happened. Bitcoin investment should be done at your own free will and what you believe bitcoin would achieve in the long run so that you will be responsible for your actions in investing in bitcoin, which will guide you to continue holding your bitcoin for a long time even though there is a dip.
The sentiment of the market is traced back to Bitcoin itself - it's not hard to see where the crowd is cheering, in fact.
But the main thing to remember is that everybody is following their own agenda - be it pro or anti-Bitcoin and crypto figures.
So they may say all they want, but you truly need to get yourself the facts and theory that would enable you to operate yourself, just listening to the news that are arising here and there.
