I know what they mean.<p>&gt; A bitcoin fork means you have to build up a group of miners sufficiently large and diverse enough that everyone trusts it.<p>Of course, you need miners. However the mining is the easy part, otherwise you need marketing, use cases, etc, for the currency to get any traction. I think an altcoin working on top of the ethereum blockchain would not be as convincing as invidual altcoin.<p>However of course if we are speaking about some other kind of asset, it might make sense to do it on ethereum.<p>&gt; Making a currency on ethereum means it inherits the trust that ethereum has.<p>No. Maybe mining security or something, but trust? Why would anyone use these crappy in-ethereum tokens, when you can just use ether itself. Or bitcoin.<p>You can make tokens as well inside bitcoin via colored coins and similar methods. They haven&#x27;t gained much traction, I doubt that they will inside ethereum.
