Any open source self-custodial wallet will be a better option.
“Self custodian wallet”…
I guess that’s another way to put it. Sounds strange to me as I’m used to calling it non custodian wallet.
Yea, I do call it a none-custodial wallet until I came across a comment by JayJuanGee (if I could remember correctly) where the reason why it should also be called self-custodial was given: "stating that the user who owns and holds the wallet has full control over it, and when one owns something and that belongs to the person alone, that's self-property". So the same is applicable to a non-custodial wallet, which could also be referred to as "self-custodial" since the owner is fully responsible for their own security.
Security: When it comes to cryptocurrencies, security should be your top priority. While some wallets offer interest, they might not provide the same level of security as reputable hardware wallets or cold storage options. Consider the track record, reputation, and security measures of the wallet provider before storing your assets.
In this day and age, information like ratings and recommendations gotten online regarding anything related to finance should not be taken too seriously, for anyone can now pay people to give a nice review and recommendations over their app. But deep down, there are things going on that we don't know about. That's why I always recommend people come to this forum to search and ask questions regarding any particular wallet, for there will always be opinions from people who have used the wallet and will share their review based on direct experience.
