Wow, that’s a lot. Why u end up having so many?

Having Unionpay and JCB as options are tempting though, I would probably ditch Bigpay because of this.
The only e wallets that you should have in your phone are Boost, Grabpay, TnG and Favepay...because they have a huge merchant base, and will be growing from time to time, don't forget that these are also the e wallets that provide decent rewards (TnG is seasonal though)...

Having these 4 e wallets are already enough (not saying that you should use all 4 of them but only consider these 4 if you wanna join the e wallet community), cuz you can use whichever that you wanna use during certain times and many merchants nowadays accept more than one e wallet (usually these 4), and when one is down, you have another one as backup.

The whole purpose for e wallets is for convenience and paying by just using your phone, and also getting rewards by making payments sometimes. Yes, our e wallets have a long way to go to be up to par with what China has, but it wouldn't hurt to give it a try and embrace the cashless society for the future.

E wallets here are all following regulations under BNM, so there's no need to worry about their server. If people are worried about e wallets, then why do people still use banking apps, how do you know it's completely safe? Just because it's a bank, but then you get CIMB with their occasional data leak and stuff, but people are still using it anyways. If you say banking apps are safer cuz they follow regulations under BNM, then it's the same thing with e wallers as well.
