In my opinion bitcoin will become more popular all over the world and the value will rise up to the maximum level. And so many investors invest in bitcoin cause they know they have good future in bitcoin.
Thanks for giving encouragement to people about the growth of Bitcoin in 2018. But it is hard to get Bitcoin to the same level as before because Bitcoin has fallen sharply. Based on information from the G20 meeting in Argentina, I think Bitcoin will only increase slightly, starting around mid-2018. Let's see if I can guess right.
