Hello there and I hope you will enjoy your stay here and be memorable when you go back to your homeland.
It would be better though if you can exchange your crypto at your place for starters.
If your card is VISA or a Mastercard, you can still use it here for withdrawals.
My friend does that every year and he won't need to worry about files needed to create another account with banks here.
The requirements will always be the problem and I bet you just want to relax and don't want any stress.
But, if you are really willing to do it then, there is Coins.ph (exchange) and Metrobank or Unionbank as a good pair.
Then, there is also PayMaya (optional) if you want your transactions to be smoother with merchants. Most of them do accept this kind of payment. That way, you won't bring too much cash in your pocket.
I hope you are using an android phone too. It will be more easier since Coins.ph, Unionbank and PayMaya have android applications and they do customer support this way.
Try to stay below Php 500,000 per tx and/or per cash-out as it might be red flagged by the bank due to Anti-Money Laundering.
Best is around Php 400,000 per transaction or total tx for 1-2 days.
If there is proof of transactions then I think it won't be a problem. Or let us just say he had proofs that he could really earn this huge amounts.
