How rich is Binance's Sister He Yi really?

Quoting a statement she once made

He Yi: My logic is that if you are going to do something, and you don't even believe in it yourself, what basis do you have to make other investors buy it?

He Yi has held Binance Coin and has only sold it once, when a friend's company had cash flow issues one year, she lent him 1 million US dollars, and He Yi sold some coins to lend her friend money in an emergency.

Let's help Sister calculate the numbers, assuming she spent 900,000 yuan to buy Binance Coin at the market price of 0.5 yuan, then she would have 1.8 million Binance Coins. 1.8 million Binance Coins at today's price of 270 US dollars would be worth 486 million US dollars #何一
