I actually know this person from a gambling site and he was quite frequent in asking loans and defaulting them. He even defaulted mine I guess. Loan was very small so I considered it that I gave him a tip later on.
You can't expect a positive contribution from them. They only are here to scam someone and make their living.
I know him (Humbertin19_) too from the same site (Rollin.io, now closed). He's not the usual scammer, I'm pretty sure he's an addicted gambler.
I've seen him win around 15 Bitcoin, and evenually lose it all. I've seen him rain ~2 Bitcoin to get attention when he was banned (from chat, not even from gambling). I've seen him give away large amounts, and I've seen him beg for small amounts.
In chat, he cries just as hard when he loses 1 m
BTC as when he loses a thousand times more. I'm pretty sure he would pay back his loans if he would have the money, but considering he's an addicted gambler, it's likely you'll never see it again.
This is my experience from a few years ago. Needless to say: I wouldn't trust him with money.
