Hey your concerns are legit but these hacking happens mainly due to you using your wallet on a public wifi, or having virus on your machine, or sharing your details like private key or seed with others. I would recommend you Electrum wallet if the total bitcoins value is less than 100 bitcoins, if it's more than Trezor wallet those are the most secured wallet
A Trezor only costs ~$95. You don't need to have $350k worth of Bitcoin to make it worth buying one.
use them only if you plan to hodl a big amount of bitcoins.
Correction: use them if you plan on securely storing your coins. Regardless of the amount.
