Okay let's say Blackjack Player A has $50k in his bank account with essentially no interest. He has $2k/month expenses and makes $5k/month from his 9-5 job after taxes and other deductions. He wants to play blackjack at a level that maximizes profit while keeping in check ROR.

How much is his bankroll that he is typing into CVCX?

How much of his bankroll should he invest in stocks, bonds, etc.? How long should this money be tied up for?

Blackjack Player A knows nothing about investing, how can he learn the +EV moves. He hears no shortage of investing advice, however, the advice sounds no better than the advice offered by 99.9% of casino patrons. Is everyone just GAMBLING!? The reason I ask this question here is because I know I can trust the responses.
