The title needs fixing too (it's a debit card not a prepaid card like advcash or e-coin).
E-coin fees are the same (or even higher) than bit-x fees (and it's not a debit card but rather a prepaid card). The usual monthly fees (and even inactive monthly fees) do not exist on the bit-x card! As it's clear, other fees apply and can be seen on the card guide page (https://bit-x.com/guide/bitx-cards). Which of those do you find too high? Of course, different people will have different opinions on these fees (which have been lowered recently, and will most likely continue dropping). Wouldn't all consumers like free services (especially so in this kind of economy)? I would. However, business costs are still a thing (until everyone accepts BTC) .
I've used all four (main) BTC card services, Bit-x, Xapo, E-coin and Advcash. The last 2 being prepaid cards. From my experiences with each (I've tested each quite well) bit-x and Xapo offer the most competitive deal, a debit card that allows you to keep your balance in BTC instead of having to exchange funds and preload the card (which isn't anything special). They're also quite competitive to other BTC exchanging services like Localbitcoin cash trades or even services which deposit fiat into your bank account, in regards to fees and convenience.
If you have any other opinions on the card please do write them here or even to the site support, but let's try to keep discussions or debates civilised. I don't own Bit-X.
