i have coins.ph also but when i expirience some transaction failed it is hard to trust again, maybe a little bit trust because i use coins.ph now for the cash out only, For now my main wallet is blockchain.
As always, just only used online exchangers to make withdrawals and conversion of money.
Online exchangers are good in terms of useful services that we can do on our bitcoin but for storage purposes it's not wise. Just enjoy the benefits of their services and never treat that as your precious storage to your wonderful bitcoins.
