BTC is not sold to anyone, it's only linked.
If you can prove you own a certain BTC address, then the coins in that address can be linked.
that's all, the BTC stay where they are, nobody takes them. The owners keep their BTC and also get free GByte.
You can buy GByte for BTC in exchanges though, and get more GBytes than by just linking your BTC, but obviously you would not keep your BTC that way.
you completely misunderstood my point but thanks anyway. You can buy and sell GB through the chatbot. It's actually a fantastic idea, it completely cuts out the need for exchanges. The chat bot has a built in order book. I've looked into it more but there's very little liquidity so,for now, exchanges still need to be used but it'd be fantastic to see people grow the chatbot order book rather than trade on exchanges.
It's actually an amazing idea, if all coins had their own built in order book you could create a sort of decentralized all seeing eye bot that could connect with all the individual coin bots and create a way to trade any coin at any time without ever needing an exchange.
Byteball should really push the built in order book, maybe offer a small incentive or something to stop people using exchanges.
