I just finished some calculations and I was pretty surprised myself when I saw the results. Such crazy numbers, I will not even share because they really look insane although they are solid. But thing is that although 1,700 or so seems pretty high, its nothing. Even double value is nothing, even ten times is no stop. Only barrier is psychological perception when price "might seem" too high for us (and yeah, 1700 USD looks like expensive number to me whatever it is), but after applying some math, I'm pretty sure it's only illusion. I advice you do your own math, don't follow just our feelings and then decide. I will only say that there might a day when we will not use BTC as a Bitcoin unit because it will be too impractical for its huge value. Sure we can see some ups and downs as people tend to panic but under current conditions there is only one strong direction in long-term IMHO.
