I think we will dip under 70 again in the next two months, but I just bought some yesterday because I keep spending them. Just don't sell them for less than you bought them for. With the way the price has fluctuated this year, it's reasonable to foresee the price going under 70 and over 120 several times before the year is out.
I agree that over the next few months the price will most likely fluctuate. I always spend my BTC too, so I've never really thought about the long term, but the future of bitcoins is definitely tough to predict.
Bitcoins used to be very accessible. Then they became popular, and were both accessible AND popular for awhile. Now they're still somewhat popular, but accessibility is decreasing, at least in my opinion. I don't buy bitcoins often, but every time that I do, it seems like they're tougher to purchase. The lower accessibility will result in lower popularity, which will probably cause the prices to drop in the long run, in my opinion.
I'm pretty sure I know nothing about economics, and I probably think I know things that are actually completely wrong, so please take my post with a teaspoon of salt
