Asking for investment advice from random strangers on the internet is a mistake. You don't know why they are giving you those answers and you don't know if they are any good.
In general, if you don't know what to do, then you should avoid investing until you do know what to do. In other words, get out now before you make a big mistake and try again later.
Strangers on the Internet can give damn advice, but there are a lot of people who can offer excellent advice to him.
I can say that this market is a big question mark, not the worst moment and the best moment. Today could be a sad day, but it was a better day than yesterday. The decision was his and he made his own choice.
