Is it even possible to invest the public funds to a decentralized market and that too in a market that has too much volatility. I have no idea about the legality surrounding it but it just looks like a publicity stunt as you cannot mess around with public funds as far as i know.
The market is soaring at an all time high and if he invest despite all the odds and the market goes down what will be his back up plan, wait until the market recovers .
