1. It is safer to use a wallet that we install ourselves such as Electrum
2. Wallet software such as Trust Wallet.
Position number 1 is for everyone's choice who has a stronger level of security and number 2 is for those who simply use a wallet and usually don't have much money.
We just have to choose a more efficient one for the wallet we use every day in this crypto space.
Of course, using a device is adjusted to what we have, if we use hardware, of course, because we have a lot and need extra security to be safer, but if it's only to accommodate prizes from bounties and telegram mini-games, I think an online device is enough as long as we can keep it from being hacked, because everything online depends on the individual.
