There are two ways to earn Street Creds in BitLife: Street Fighting & League Fighting. If you compare both, the Street Fighting is much quicker and rewards a lot of Creds. Players can use the Street Creds to purchase new fighting moves, recover stamina & even hire a new coach for their fighting career.
The Street Creds are in-game currency in BitLife that help players get new skill moves and improve their overall build. So, if you are wondering how to get more Street Creds without spending much stamina, here is a detailed guide on how to do so.

There are two ways to earn Street Creds in BitLife: Street Fighting & League Fighting.
How to Street Fight in BitLife
To start a Street Fight in BitLife Ultimate Fighting Mode, press the Street Fighting option under your Fighting career tab. Now, in the list of available street fighters, find a suitable opponent according to your current skill level. For example, if you are a Level 3 fighter, you should try to find any street fighter within the range of Level 3 to 6 as your opponent. Too high, you will be defeated easily, while opponents of a similar level will reward you with very low Street Creds.

Before starting your fight, ensure you have equipped the best moves for your build to fight better. Also, since this is a Street Fight, I suggest taking some juice (Steroids) to gain extra Stamina, which will further increase your chances, and there won't be any doping agency to ban you from participating in future fights. Keep defeating opponents to gain as many Street Creds as you wish.
How to participate in a BitLife League Fighting Match
Another way to earn some Street Creds is to take part in League-sanctioned matches. These matches are pretty tough as you cannot use any illegal moves & not take juice. So, only equip your strongest legal moves and get ready for battle. Click on the Fighting League button inside your Fighting career tab to open the list of fighters in the League. Now, either pick a fighter a rank above you or below you. For instance, if you are ranked 8th in the League, choose the 7th-ranked fighter or the 9th-ranked as your opponent.

The best part of fighting in League is that you can earn a lot of money, fame & XP, along with Street Creds, which enable you to position yourself as an elite fighter in the League.
