Maybe it is only circulating in the Philippines.
I no longer use coins.ph now they are competing with a lot of good exchange wallet like coinpayments and enjin.
Coins.ph is a great help to Filipinos that are trading bitcoin and now ETH too. Though the thing about coins.ph is that they are only an exchange of BTC and ETH unlike these two exchange that is mostly accepting great crypto currencies. As an exchange, coins.ph can't compete with these big exchanges but as a Filipino BTC and ETH wallet, it is a great and the best wallet, can't say that it is secured since it is an exchange right?
It's not the best wallet for me it's one of the best site to buy or cash out bitcoins and you're right that it's not safe to use them as your main wallet. Users from the previous page already mentioned the new exchange of coins it doesn't offer a lot of altcoins but at least it's a start for us and for them so we could trade altcoins with fiat.
I am actually trying to find this wallet in my coins.ph, wallet in my android device, what I heard to other users you can just slide it to the right until the ethereum wallet appear, but in my case, I don't see any ethereum wallet. It's weird because other users said that the wallet is on the right side of bitcoin wallet if I swipe it to the right.
Your not alone mate my app is also updated but I haven't got any update about the ETH wallet. Let's just wait maybe there's still bugs or they want the implementation to be smooth before releasing it to everyone.
