It is not a Future - it is the Present!
You can already trade it and you can even have it as your Account Deposit and/or Balance!
For your information 1 BTC was 0,50 $ cent in 2009 and that same 1 BTC is now close to 5000 $ today so you might be a bit late with that.
No the concept is valid.
But indeed there is a capacity issues, people are working on this and that is why it forked recently.
Especially the cryptography involved, is extremely solid, and usable in so many applications, other then (just) online banking.
In the near future, excitement with Bitcoin (and other crypto-currencies) will sometimes grow, sometimes fall. But the fact that in the end everything will end, is definitely understandable. Because the same, like, was, for example, in the days of Tulip mania in 1637, see Wikipedia:
Then (as well as now Bitcoin) suddenly tulip bulbs became very expensive (it was the first ever bubble in history). Then you could buy a house in the center of the city for two bulbs of tulips.
Then the market participants came to their senses, the bubble burst and everything fell into place. The same will happen with Biycoin. However, when this very moment of truth will take place, it is not known. But this return of the status quo will necessarily happen.
I do not believe in Bitcoin (and money is a matter of faith) and in other crypto-currencies. I think they have a future like the bulb of tulips at the time of tulipomania: That is, the soap bubble must burst. But if a trader turns out to make money on the movement of the price of a crypto currency, then of course you have to earn! Why not?
You can't just compare a cryptocurrency to a flower like that.
That's like comparing water to a peanut.
Marco, money is also a commodity.
