Decreasing and increasing is a possibility, and it's better not to quickly believe in other people's predictions, and better do your own research to make a profit. A decrease of 1k is indeed a possibility if bitcoin is abandoned, but I don't think it will happen this year.
Hey these are baseless statements made by the so called experts, with the sole aim to cause panic among the investors. They have tried saying these numbers year after year, but it has never happened and it will never happen again. I believe one should ignore these experts, and do their own due diligence or else they will end up making losses.
if they are that good they would have made a lot of money in future trading. The fact is that the market can go either way and I won't be surprised if there is another bear rally downwards before the next rally, one thing is certain that everyone believes in another bull run that could cross yet another all time high valuation , but it is difficult to pin point the exact time of the rally until it happens.
