Your daily, monthly and annual transaction limits are currently affected only by incoming and outgoing transactions to your Peso (PHP) wallet. This means that converting XRP to PHP will affect your limits (because funds are going into your PHP wallet). However, converting PHP to XRP will not affect your limits.
Sending and receiving XRP between your Coins.ph XRP wallet and other Coins.ph XRP wallets or external XRP wallets will not affect your limits.
For more information on transactions that affect your limits, see here. To learn more about daily, monthly and annual limits, as well as increasing your limits, see here.
