This was a no-lose scenario for BCX, just different sorts of wins.
For the most part I would agree with this. But if I were BCX I would find the hit to my reputation a bit hard to reconcile. In the end he just was a lying manipulator. And perhaps this is enough for him to have fun.
In the end his credibility was badly damaged by this.
BCX! Crusher of Solidcoin! Destroyer of Auroracoin.
Played peek-a-boo with Monero.
Doesn't really continue the legacy does it?
Sure, just depends on the legacy that matters to BCX. All that remains would be for BCX to claim victory. After all, BCX got everything BCX asked for from the outset.
We all can see how BCX's crushing might of brute force hashing, summonable on command plus a deep history of expert TW assaults and DDoS capability of BCX's repute, has forced the hand of the XMR dev team to alter their commits just to address this threat.
That the DEV team also came to BCX, hat in hand, asking publicly for help from BCX shows their both humility and single-minded dedication to the success of their project. They dropped all pretense of ego, all they care about is tight code. They seem willing to admit that given enough power, the block chain, any block chain, can be overwhelmed.
They did manage to raise the barricades a good bit, and battened down the hatches with their decentralized and nimble checkpointing innovation. This would make any TW dependent attack much more costly to BCX with much less disruptive effect.
XMR is in the crib, in the years to come it will have to contend with much greater adversaries than BCX. It was born out of a litter of CryptoNote alts, had a brief foster parentage with TFT, and now has a strong well balanced family of its own with its current team.
There is no perfect offering, XMR just managed to achieve "best yet", and within the 72 hours of the BCX challenge issued. Other baby alts would be wise to follow this leadership in TW defenses.
There are TLAs more powerful than BCX. Thanks to BCX, XMR is a bit more ready for those challenges to come.
