Yes. I think the bitcoin price will be between $5000 to $20,000 in 2020. It is due the general usage of bitcoin.
After a few hacks, and there is no good user experience, the bitcoin price could go lower and it is replaced by another coin.
the rate of bitcoin is stable or not, its depend on the market and condition people to buy and sell. if people react in bitcoin in positif then bitcoin can more growth, but if not, bitcoin will get falls. enthusiastic people to bitcoin can give good effect for bitcoin and maybe bitcoin from year to year will be growth and gets stable.
The bitcoin price shall not fall much in the next few months. The hack just happened to one exchange.
If there is no further bad news about the bitcoin, the price of bitcoin should start rising in the next few days.
