Before strategy, before models, before picks: decide what one unit is. Betting in fixed units — a small, consistent slice of your bankroll — is what keeps a cold streak from becoming a busted account, and it is the convention every Covrr stake suggestion is built on (1 unit = 1% of bankroll at moderate risk).
Enter your bankroll and risk appetite to get a concrete dollar unit. Conservative (0.5%) survives 200-unit downswings; aggressive (2%) grows faster but hurts more. If a losing week would change how you bet, size down.
