I've got a question regarding Ethereum in general.
Let's say ETH falls apart with it's price.
How does it affect coins which are based on Ethereum? Do they also take some damage or something?
How they're connected with each other if at all?
Another thing is - I've read somewhere that ETH founder (Vitalik Buterin) can wipe all of your ETH with one command or something like that. Is it some meme or is it actually true?
Ether and other coins that are based on Ethereum network are tokens that are supported by the network. So they all use same blockchain (and ether is the one needed for the user to pay a fee to the network, no matter which token you use). WHich makes the Ehter no1 out of others. Still other tokens price doesn't need to be much related to Ethers price.
They are conectet by the Ethereum Blockchain and they all are tokens on it - they run as a smartcontracts on it.
He can delete all the coins but if he do this however I am sure that there would be another split (like the one that happened in the past and we have ETH and ETC). He can try to delete it but people can just take one block and say we copy all the block ending with block XXXXXXX and make a new version of ether.
