the price of Bitcoin is not stable so we should expect a particular amount by the end of the year,
We can't be expecting a particular amount by the end of the year! Bitcoin prices change on real time. If it was possible to know the particular amount it will be by the end of the year i would take beneficial actions know because i already know what would happen. Perhaps you have been listening to speculations from people around you or online, i want to tell you that those are mere predictions, it is bound to happen or not so an investor will fail if he Soley relies on it and take actions regarding it.
