How can I safely store UST?

I have my some money in USDT and recently I've decided it's probably not safe holding big money in USDT. Guy from Coinbureau holds his fiat in UST and I think that's a good move. But I don't think he mentions where he holds them. Now I love Binance but unfortunately it doesn't support UST yet, but even if it does, I wouldn't want to keep a huge amount on an exchange. UST is not supported on my trezor one or trust wallet. What I'm hoping for is that there is something as safe as trust wallet to store UST.
