im also from the ph and i also use coins.ph as my primary wallet to cashout or exchange my bitcoins to local fiat and then withdraw it via a remittance center. i dont use atm bank as withdrawal option because mainy coins.ph user said that atm withdraw is verry risky and most of the times they lost their money after they request a withdrawal in an atm bank which is security bank specifically. they also contact the support of coins.ph but they dont get any direct reply form their team.
Back to topic cashing out your coins would vary on which country you do live on and find the suites your taste and speaking on fees I don't even know since they do really have different fees on each one of them.
