Trezor would be the best investment you could ever make.
Just to add, Some ppl can't afford to buy a trezor since their investment in crypto itself is much smaller than the cost of trezor. You should recommend other security tips like using paper wallets, never save your seeds online, etc. And once their investment gets larger over time, they can switch to a hardware wallet.
P.S.: I hardly use a hardware wallet for myself, but Im still safe coz I know what precautions to take
I researched some hardware wallet that might be useful for more security for investing in crypto. But I might try to wallet apps first, since I still don't have much that money on me right now to invest in hardware wallet, as much as I would like to buy one right now.
It is better to use a hardware wallet to hold the crypto. I am using a safepal hardware wallet. When it comes to a trust wallet, there may have a possibility of getting hacked. They have only 12 phrases in the seed phrase. Also, there are a lot of other options like cold wallets and hot wallets.
I am thinking of buying safepal as of now, when I searched and compare the prices between safepal and trezor, I would go to safepal. But when it comes to security, I would go to Trezor, as my friend suggested as well. We'll never know. Maybe in the next few months I am gonna be able to buy hardware wallet. But again, as of now, I am just gonna be using crypto wallet app for now.
