What is the best?
Counterparty +
Omni
Ethereum
Nxt
Waves (like Incent) +
BitShares +
..
Research them. Each of them have advantages and disadvantages. You can actually issue your asset on all those platforms. I don't think is expensive, on counterparty cost 0.5 XCP and when finally decide use the best one that will fit your project most.
Do you mean start the same name cryptoasset every platform?
Funny if any exchange will accept this scam
Yup, exchanges will just throw you out. The problem is not with copyright violation. The problem is that the scheme is trying to scam people into buying a new alt using established names. That won't work.
In the real world, you won't be able to call handbags that you make Gucci and sell them on Amazon.
