I think that at the end of this year it will be more realistic to see such figures as Bitcoin costs 8000 dollars, and Ethereum 400, can a maximum of 500 dollars.
Hopefully price of bitcoin could reach to 8000 at least we can see it increases from current price. Same as eth that most people expected to increase in bt and eth.
I think that 8000 is quite a realistic scenario. but at the expense of 12,000 I doubt very much, as well as at the expense of the fact that the price of Bitcoin drops to 800 dollars.
