The ones I used are Kucoin and Binance for staking altcoins as they are probably one of the safest wallets out there and with the highest returns. Though they are centralized, you don't need KYC to deposit/withdraw your funds anytime. But since they are exchanges, you should be aware that you don't the key to your assets and you should use it with care.
Kucoin and binance aren't safer wallets, they are centralized exchanges, how do you feel relaxed when you entrusting your altcoins to centralized exchanges? This is why I don't use exchanges for staking, you have to control over your coins anymore and that's risky
While I can agree with you, I am still using Binance and Kraken for staking my coins. It is not a massive amount, it is easy, good returns and in my eyes still quite secure.
In fact I don't really use wallets, I store most of my coins on exchanges.
