Lots has been said on this topic.
Personally I believe Bitshares will become the first trillion-dollar crypto, but I'm slightly biased.
Bitshares has the potential to completely reboot global finance (bitAssets) and politics (Vote). Sounds grand, but is real.
The recent announcement of Google's billion-dollar investment in Musk's satellite internet program is the harbinger of a perfect storm.
Bitshares + Global Internet + Cheap Smartphones = Revolution.
Just for a little circlejerking I'm saying $1-$5/BTS in the next 2 years/by 2017...
You must think Bitcoin and other cryptos are going to boom over the next 2? I think it'll be a while before Bitshares is able to detach itself from the crypto enthusiasts economy.
My personal belief is that Bitcoin is following a scripted adoption plan:
Grass Roots (Crypto-anarchists!) -> Small Biz -> Bigger Biz (basic infrastructure) -> Wall Street/Hedge Funds -> Sovereign Wealth -> Small Gov -> Big Gov -> Main Street (fiat is pushed into forced obsolescence and everyone has to use addresses linked to gov id and white coins).
Currently in the Bigger Biz -> Wall/Street Hedge Fund phase where BTC gets pumped to the $100k range, setting the stage for the big boys to move in.
I think this is playing out in parallel with the impending market collapse/debt contagion fiasco, with bitcoin as the scorched-earth option in the currency war we are witnessing.
So yes, I think over the next 2-3 years Bitcoin is going to boom like nothing has boomed in the history of humanity.
But Bitcoin is just a protocol, like http. BitShares is more like the entire internet ecosystem, but for finance and voting, with a twist - BitShares is monetized via BTS and decentralized via DPOS.
BTC and BTS will happily co-exist, but I believe BTC will exist as a small part of a much larger BTS ecosystem.
