Like everybody else, I would would suggest unregistering. Great win to get into the warmup, but the odds
of you going deep against a decent quality field is slim, so take the T$!
Although on the other hand, the gambler in me is saying, go for it. The chance of winning a big check is always in the back of peoples heads, and usually has the most control.
Its your money, so do what you think is right, but knowing that you were playing $3 sats, leads me to believe that $200ish is a big increase in your bankroll.
Hope I could help, Goodluck either way!
