Can someone advice me if this split would affect the price of bitcoin anyhow? If yes how?
The "split" like you call it, was resolved by the network 6 blocks after it happened - which shows how resilient (or anti-fragile) the Bitcoin network has become. Regarding the price of bitcoin, please go to the speculation section of the forum.
It requires manual intervention, so anti fragile my ass!
Also where is the 6 blocks figure from? Your ass?
It just requires you to keep your software up to date.
It's like having a website and complain to be hacked, just because you didn't install security patches.
Do you also want the dev team to wipe your ass?
ElectricMucus is right, it's not anti-fragile at all unless you think the Bitcoin fairies are magically keeping everything patched and updated for your downloading enjoyment. Someone has to monitor the system like a 24hr a day security guard. Nothing is automated. Every version of Bitcoin core after 0.9.5 can detect invalid blocks. Web wallets, SPV wallets and core 0.9.4 and earlier are still vulnerable to double spending. They need to wait 30 confirmations to be safe. That's the complete opposite of anti-fragile. That's more like fucked-in-a-hand-basket. I can't go to a store that uses SPV devices and buy something because I'll need to sleep there overnight to wait for my money to clear. What would you do if you were in a restaurant with family and pulled out your debit card to pay and the cashier told you to wait for a few hours because your bank is having a problem. I'd shit bricks. I'd close every account I had at that bank immediately and talk shit about them to anyone that would listen for the rest of my life.
That doesn't change anything about, that in this case, people had just to keep their wallet up-to-date.
If your web-wallet provider wasn't up-to-date. Sure, close your account there. Find one, who takes his job more serious. (I actually changed my bank half a year ago, because my former bank's online banking sucked)
If you use a SPV-wallet, make sure to connect to an up-to-date node.
And yes, there is no Bitcoin fairy doing that for you. I can agree on that.
