I was satirical. My honest opinion is that bitcoin is not dying, that it won't be replaced, and if it did happen it would be a disaster for the cryptocurrency space. All coins would suffer tremendously if it takes that little for the next coin to come along and replace current. A lot of faith would be lost.
Monero is what I look at as a complementary currency.
Agree. I think what a lot of alt-coin folks fail to appreciate is the potential disaster to the entire ecosystem if Bitcoin falls from dominance - it puts the validity of the crypto-scarcity idea itself into play for the first time.
This is also why I think Bitcoin's blocksize-limit absurdity is so dangerous. By potentially becoming high-fee on-chain, Bitcoin is handing a whole bucket of Bitcoin's key transactional (ie, use-as-money) use-cases to alts for the first time. Demand for cheap high-security tx will be met one way or another...
That demand can easily be met by Bitcoin if various parts of the community would get their heads out of their asses. And if not met by Bitcoin, that demand will clearly be met by something else. That something else will obviously gain a good deal of value, both from the transactional flow itself, and some speculation layered on top of that. But if it seriously looks like bitcoin could fall, the long-term crypto store-of-value thesis can easily be said to have serious flaws, and that'll strip away the store-of-value speculative premium from the *entire* crypto space. And since wealth storage and gold-like use-cases are *by far* crypto's biggest potential in terms of driving market-cap, it could be a huge shock if that speculative premium disappears from the space. I think this is what many people wishing for their alt-of-choice to overtake Bitcoin fail to fully understand.
FWIW, I also agree that Monero can be a nice complement to Bitcoin, should Bitcoin remain #1.
