3. My favorite utility wallet is Trust Wallet, I can easily open all dApp from there and put all of my wallets in one app.
There is still nothing worse than close source softwares and apps, Trustwallet is completely a close source wallet, you do not even know if it has spyware or not, I will rather use an app that is completely open source for Bitcoin. Why not then try open source hardware wallet if you have hundred of dollars worth of altcoins.
The reason for the use of an open source wallet or apps is just for security consciousness but it can also lead to the vulnerability of the wallet.
I don't use the Trust wallet at the early stage, I started to use it when they partner with Binance and when I checked their features then the Trust wallet was an
open source wallet, not a closed source.
