well, this year started on a wrong foot for bitcoin with lots of uncertainty and wavering prices that led to panic and uncertainty. but as we have seen, BTC ia back and it will only sore higher. the graph represents a strong case that that i concur with, if the growth stays steady, no matter how slow the pace is, BTC shall hit $20000 and maybe pass it.
I also think that it can exceed this point and even go on growing. I can guess that 20 thousand will be not a limit to Bitcoin, and BTC will soon prove it.
