My opinion is that its very much 50/50 for Bitcoin at the moment, its possible it could be completely obsolete and useless in less than a few years as more and more contenders for the top spot develop and build better running block chains.
Or, It could very well go to the moon which is why now would be a very good time to buy in if you havent already.
All in all, just another day in the world of crypto-currency.
That's a possible outcome. However, I don't think Bitcoin is likely to become obsolete. For a few reasons, but mainly because it is has the largest foundation and its scarcity makes it a great alternative to gold for both store of value and speculation. I think because of Bitcoins immutability and capped (low) supply, many will use it to store their wealth. Eventually, some governments could even start hoarding BTC as part of their reserves.
