Actually, there is a real new bitcoin, but it's not ethereum, which I feel is made not so much for use as a medium of exchange but to run applications off of it's blockchain. I think that ether will be a very profitable investment, not as the future money of the world, but as a token which smart contracts and software will use. The true new bitcoin just was released yesturday and is called ZCash. ZCash is basically exactly like bitcoin, only with anonymity. ZCash will likely become much bigger than bitcoin, but will at the very least replace it.
