Son is 18. That’s about $43.5k USD. For reference, I earn ~9000 lei per month, and that’s considered a very good salary here. There are still people working for ~2500 lei a month. Son forgot to close this Revolut tab on the living room PC, that’s how I came across it.
Possibly money mule. Could be holding it for a time then will transfer it out later. Your child’s percent could be taken then.
