Other early bitcoin hoarders might be - 100K btc would almost get you three commas. That may have cost $1000 maybe back in the day. To have $1bn and still code full time, it would have to be 'hands off' money, which is rare because to make that much money you'd probably need a wildly successful business which you kind of need to manage yourself. Someone else mentioned trading firms, that might be one way, with enough luck and negotiation skills.
