Ironically, I had the same discussion with my colleague about how coins aren't shares.

At some point blockchain ideas are going to come to fruition and in business, acquisitions will be rife. Just think right now Ethereum should pick up Quantstamp and not let it migrate to other networks like it intends. It would become another feather in Ethereum's bow.

So if company X buys company Y, what happens to the investors? They get nothing as the coins have no rights, the buying company could say "tough!" and there is no recourse. Imagine that on a company with a market cap of $1.5bn or something crazy...

Or, even worst, if using DPOS, can an investor come in and buy enough stake to take the voting rights to dictate the network? This is how hostile takeovers happen with shares.

This is why I'm confident regulation will occur. Right now it's the Wild West and no one quite realizes how bad it could get once the violence starts. Think back to the .com bubble... Businesses just vanished over night.

I keep saying the future is going to be very interesting... I can't wait.
