Due to the recent massive decline in eWallet value for GRAB (used to be x20, x9 then x3 and now required even more points to redeem stuff) and Boost (more points required for exchanging cash with lesser value), and Bigpay point is difficult to earn if you are just using for topping up eWallet.
Consider you only earn 1 point for every RM10 spend, to redeem a flight outside Malaysia one way will cost at least 10,000 points......

As for touch n go (only good if there is a campaign running, otherwise you don't get any benefits out of it).

Is eWallet still worth it?

I would personally go for NO, and switch to using credit card with cashback instead or switch to card that gives me at least x5 and x8 points for exchanging vouchers in future.
