If bitcoin did not exist and tomorrow there would have been the ICO of Bitcoin, would you buy it? Or would you invest in other projects?
This is a truly original question. I would give you merits if I had any. If there were all other coins around, but bitcoin was on ICO stage, I guess it wouldn't have survived on the market. People would say something like that: what is the product for the btc project? What's the project really about if we already have blockchain? It doesn't even enable smart contracts! Oh, and the transactions are really slow. Who's the coin's creator? No team leader? It's probably a scam!
