I don't know exactly what are your plan for redistribution
But consider making it "IPO style"
10M coins that will be devided according to one's shares of INT
In case that not all INT will be claimed it will benefit current holders
Yea, that's what I was thinking.
Have an IPO and make people buy INL with their existing INT.
They can also purchase INL with BTC but people with INT will have a better exchange ratio.
