That's right. No hot wallet can be better than a cold one. And I think that every crypto enthusiast, if he gets rich, goes to trezor or ledger. Because these are really reliable places to store large amounts of cryptocurrencies!
In the meantime, I have small amounts of cryptocurrencies, I use Electrum and TrustWallet.
At the same time, I consider Electrum to be more reliable, because its source code is open. And even if the Trust Wallet was made by people associated with Binance, its code is closed.
It all depends on the deposit and how each of us treats security. For someone,
X-wallet is reliable, for someone else it is not. This issue can be solved only by diversification. For me personally, most of the hot wallets are perfect. And for someone else they not.
P.S. It all depends on the individual, put your choice on the device you trust. At the same time, do not listen to anyone. This is really the most workable method. You can discuss it for a long time, and in the end you won't find the ideal for you.
Hot wallets are less secured than cold wallets, they're more vulnerable to attacks because they're connected to the Internet.
If you feel that way, switch to cold wallets. Or make your own. There is quite a lot of information on this subject on the Internet.
