If it's going to be a stable coin then it's not something you want to buy as an investment, just something to use. As a speculator you will want to stick with bitcoin instead then change to globalcoin when you want to buy something
I agree it will be heavily regulated might as well stick to Bitcoin and other top coins in the market, but we'll see I don't want to judge how this coins going to perform, but I don't see it as another threat to Bitcoin although some people already speculate the possibility.
