That's undeniable that bitcoin's price can still go down as low as $2,300 but I think its trying to stabilize now @ $3,800. We will see if what you are saying is right.
Everyone is free to speculate the price of bitcoin and tell his own prediction. But opposed to the news applicable for 2019, most of them are positive and can impact the market positively.
By the summer of 2019 the price will reach 10,000 dollars
It can go as low as these predictions but it can also go up unexpectedly.
