I saw since last week all cryptocurrency market big dumping with major currencies. So i want to know end of this year will cam reach btc 12000$ and 800$ values with new cycle.
No one could really tell you the right amount but you can expect the result already if you know how to read the charts in the market. We already know that cryptocurrency is very unpredictable in terms of volatility, so you can't expect a right answer here for the result of your question.
You will have a choice to either read the chart for the speculative price or keep asking here even if you already know the answer to your question.
