I agree it will have some impact, but why do you think it will be such a deciding factor?
It may be a bit to early ... but IF the coins 3.0 wont get dumped and then crash VERY bad,
it would be similar to a deciding battle in the war against Fiat currencies.
So for me the success of the c3.0ins ^^ would be the gamechanger big time even for bitcoin. ~over1000�/btc/maybe;)
On the other hand if its gonna be a dump ... it might be a setback of at least 1/2 year for all cryptocurrencies.
And i would loose a lot of BTC and that wouldnt be good for my retirement funds
anyway nobody knows what the stampede of the islandish hordes gonna be like ^^
