2015 will be all about sidechains. It's an altcoin pump and dump killer. I suggest a boycott of all alts until then.
PS. there is already a coin called 2015

sidechains is bullshit and could easily turn bitcoin into a shitcoin.
I suggest the contrary: diversify in alts until then and wait it out about 6 to 10 months in case the experiment with bitcoin goes wrong. There is high probability sidechains create some serious trouble for bitcoin.
What kind of trouble?
new possibilites for exploits, new possiblities to spam the blockchain, further blockchain bloat - thus making one of bitcoins most serious problems even worse.
It's a stupid idea to implement that into bitcoin especially without testing it in an altcoin before. Complete BS from my perspective.
If it ever were a success (i doubt it) - it would be implemented in a lot of altcoins too, thus no big deal at all.
Dogecoin will probably be the first alt to implement that too... it's just exposing bitcoin to more risk, that's all.
Normally innovation should be tested in an alt before implementing into bitcoin. In case of sidechain the morons obviously want to test it in bitcoin before altcoins will copy. So i have no idea what's actually happening and who is making the decisions.
If there's no consensus on it won't happen anyways because the hardfork of btc which would be required could easily backfire and end bitcoin right there. I don't know though if the network is centralised enough and they can just do a few deals in the backroom to change bitcoin however they want already. So maybe mining in btc is already centralised enough they can change it however they like. The sidechain-thing could easily reveal that.
I see sidechains as a threat to bitcoin and not a threat to alts tbh.
