"In real, non LC life" meaning LC is not allowed as an answer? This is my main source of income. It pays the bills and nets a decent savings on top of that. I find this p2p stuff is more relaxing and certainly more stable than other things I could be doing.
But if that's not allowed... I retired from software development 15 years ago in my 20s and now use those skills to come up with whatever schemes will make the most money in the shortest amount of time without human intervention. For example card counting blackjack bots. Backgammon for money. Sports arbitrage. Video game currency exploits.
