Advise,
If you're interested in using hot wallet, there's more danger in it than when you're using a non custodial wallet, you can only use hot wallet for a short time trading or exchange of currencies, but as for your storage of asset, its not a safe zone for use.
Since you are advising people on something as serious as use of a proper crypto wallet, the least you can do is to actually know what you are talking about. If you bothered to check what hot wallet actually is, you would realize that it can be non-custodial as well.
Having said that, hot wallets shouldn't really be used be used for a long term hodl (at least I woulnd't) even if they are non custodial and open source.
