Why sell %?

[Saborion]

Why would someone who can afford to play in some specific tournaments want to sell a percentage of his possible winnings?

To cut down his expenses and change the risk vs the reward?
I don't buy that since, as we stated above, he can afford to play in those specific tournaments.

Because he's not sure he's good enough to come itm?
Well then maybe he shouldn't be in those tournaments in the first place?

I can understand the pretty good player who think he has a shot at winning some $10k buy in tournament, but those $10k is still a bit too much for his likings. But someone who has a BIG BR, why would he want to sell percentages?

Or as I just saw, a player that just got itm at a $200 online tournament ($200 who he EASILY can afford), only to have a discussion starting between himself and another person regarding a possible sell of percentage?
