It may not take up to that long I'm just giving my prediction, Lol. We never can tell what will happen in Bitcoin I'm not too interested on Bitcoin reaching 100k since I just started my accumulation However if it happens this year I will be happy so we can now set a new target of reaching 200k.
Me as a newbie all I'm interested in right now is accumulating as may Bitcoin as possible. Bitcoin could hit 100k this year or it may not however I'm really confident if it crosses this year without it hitting 100k it won't cross early months of next year.
