Among the soft wallets, MetaMask wallet and Trust wallet are considered very good which you can download for free.
Trust wallet is closed source and i will not recommend it or MetaMask for someone who is looking for a wallet to store only their BTC. I don't recommend people to use multi-coin wallets to store their BTC and other shitcoins, it is better to use Electrum to store your BTC's safely and then choose another multi-coin wallet for all your other cryptocurrencies.
We are aware that hacking bitcoin is not so easy.
BTC in itself cannot be hacked, it is not centralized, but people who have BTC in their wallets can be hacked and their funds would be stolen, but that is if they have bad operational security or are just unlucky.
