I see! Thank you for the break down, meaning I shouldn't be using MEW or trustwallet anymore?
What I meant is that the wallets are not recommended.
For long now have been that two wallet but I found no problems using them, maybe could it be as results that I didn't have enough coin/token inside that is why I am not being targeted for hack or scam?
Being close source only means the developers can create a backdoor that users do not know about, unlike open source wallets that the public or other developers know its code.
Sure, for long never had anyone talking about MEW, instead trustwallet is mostly valued and if not that you said they are all close source meaning its a redflag?
Yes, being close source is a red flag.
