I think that bitcoin has a very prosperous future and will continue to increase in value. Unlike fiat currencies out there it is not susceptible to inflation, as it has a fixed quantity of 21 million that cannot be altered. If governments want to make the debt in their currencies worth less, they can simply print money, but Bitcoin will never be at risk from that. If anything, the amount of Bitcoin in circulation is likely to fall over time because small amounts get lost in old wallets or access to wallets is lost for a whole variety of reasons (viruses/owner death/etc). It's great that the value of Bitcoin is falling though, because that means it is possible to buy more for a cheaper amount in the dips - you really have to think long term.
The big advantage of bitcoin once being embrace by many this what you have said, due to the numbers of coins to exist over the demands of many people who will going to use it.
We can't tell when but with how it's moving right now then we can say that new ATH is really nearing, hard to predict as if this continuous uptrend greed may take place.
Instead of selling it with a better value it's nature to think that it may rise more, you should
have your specific target and be content once it's been reached..
