I just found out that even if you open 100 ETH addresses using Metamask, once your key is been compromised all the 100 ETH addresses are gone, but in case of Trust wallet each addresses has different recovery seed ..
If you don't know this before you should know now, please take note, some people are using Metamask multiple wallet addresses and they don't understand the risk involved.
You have a point but do you know that Metamask is better than Trustwallet because is it completely open-source while Trust wallet is not even though they claim their wallet is open-source?
Meanwhile, the most important thing every cryptocurrency need to understand is the pro, and cons of using every crypto wallet they use to store their coins and they also need to avoid human error.
Metamask is not fully open source.
