I am interested in creating my own altcoin that will be minable through a phone app. Can I copy a existing coins source code, edit it a bit, create a whitepaper and launch a ICO for my coin to collect essential funds for creating the phone app, wallet, marketing, etc. I really don't want to create something on the Ethereum platform since I don't know Solidity and most Ethereum ICOs look like a scam. What do you think is this the way to go if I want to create my own altcoin? Also any developers who would be interested in teaming up with me feel free to PM me.
