between all wallets, ETH wallets, Tron wallets, Ripple wallets, waves wallets, NEM wallets. and in your opinion, which wallet is safer, better, and easier to use for transactions?
Can't compare those as all you have mentioned does have a good wallet based on my experienced. Kind of user friendly to me
(Except for Tron. Didn't have an experienced using their own wallet). The interface and way of using is easy to understand. For speed of transactions, it depends on their respective network.
In terms of security, honestly it should be started to the user itself.
Protecting private keys at any means, staying away from sh*t site or something simila that may lead into phishing etc. are just few of a basics things to do when dealing about wallet security.
