he claimed he spent half a million on his wedding. If he's being serious and that's in his native currency isn't that nearly 10k USD? That would probably be a very elaborate wedding by Philippine standards.
According to
the first site I found, over $8k is average in the Philippines.
The audience that site appears to target is Americans thinking about traveling the Philippines for their wedding. That figure includes costs for airfare and lodging (apparently only for one person, though,) which are costs the locals will not incur.
It still seems outlandish for weddings to cost so much. The average income in the Philippines is under $4 USD per year. I know they're cultural differences, but it seems like in the Philippines it's an industry rife with vultures.
Would that be the case if the Grandson had two or three times the average annual income worth of bitcoin in his possession?
