Basically, the title above, but the more I see the world, the more I realise how easy it is to rug-pull people only if you have some credibility behind your name, and bonus if some military power.
When Nixon rug-pulled the world in 1971, it seems nobody even said a peep, and everyone just carried on as if nothing really happened. Part of it may be America's military might, but it seems most of the world did not even think of it as anything significant.
Now that Google is releasing its L1 blockchain, doing god-knows-what (I could not bother to look up yet), I have full confidence that if they eventually release something like G-Coin, people will totally trust it as money, who will buy it with their fiat, and may be it will allow tight integration with the whole Google eco-system (of users and services)-allowing you to send it to any other Google user by an app, pay in the app-store, on-ramp with Google pay or whatever.
And, may be, Google will keep the game on...for 30 years, 50 years...who knows, before they collapse, rug pull or inflate enough for people to realise it. But I have full faith in peoples' stupidity to accept the latest Shitcoin in the block, which comes with the added credibility of Google behind it.
And, of course, someone will also say G-coin is so much more useful than my sats to buy a coffee or for an app-purchase (no kidding, as Google will go full bore to support it on every device and platform they can).
