Stay put, do not go that sandtrap, play offshore and get a good local, LV and the Sportsmarket are no more, you have to do immense legwork just to bet a few dimes at generic numbers.
Billy Walters(widely hailed the greatest sportbettor ever), Bob Martin(widely regarded the greatest BM ever), and Stu Ungar(considered by many fellow pros the greatest poker player ever),etc..all share the common thread of having went broke numerous times and needing backing..and they played in eras of a much more beatable sports market.
Most all wiseguys and pros that I've known, and/or met, despite connections, information, softer markets, and having gambling educations you'll never know..have went bust numerous times..quite a few after having to never need again in life should they stop and walk away..some lucky to win it again, and/or later in careers if wiser, or get fat and walk while fattened up large into other endeavors..or before divorce, their health, and/or the many tolls of gambling(legal, familial, social, spiritual, physical, etc..) ravaged their lives on solo or multiple levels..
And 20K isn't a real "moving to LV" sized bankroll, stay put, learn your craft from home, LV is a rough environment full of vice for ones lacking extreme discipline..
Go to LV only if prepared to stay in your banking industry, and attempt to supplement your income via Sportsbetting.
Being twentysomething and heading to LV with "any" sized bankroll to be a pro on your own devices is foolish at best.
Be careful what you wish for!
