One Hundred Dollar bitcoin for now seems to impossible since it continues to rise as years pass by. It might not be possible unless bitcoin will die. If it were to die, it will came back to 1$ or even less but it dying won't happen soon in my opinion. Instead of waiting for that, earn free Bitcoin now while you can since it's future value might be good so hoard and save bitcoin now for the future.
Well you are right about that i guess theres no big problem that will create any downfall bringing btc price to 100$ but one thing is for sure just by looking on it seeing more and more progress that keeps happening much prefer to say that its getting near to 1k$.
What I see is that when the price of bitcoin will rise it means that it is progressive and good development is happening and when the price fall back it's the opposite thing that is happening, so basically there's a big problem with it and to think that the current price now is $700+ and will fall back to $100.
It's a big downfall already that might cause panic selling and bitcoin might lose the trust and confidence of the people.
what fall is that, you are not making any sense!
if you take a look at a price chart starting from 2009 and zoom to a level that it shows all the prices from that time until today you can clearly see that "apart from the MtGox fake pump to $1100" bitcoin price has only been rising with no fall whatsoever.
and this is because of the adoption, development is also happening in the meantime but it is mainly because of more people starting to use bitcoin or invest in it.
