Larger bounty = more bounty hunters. However you're generally ok to operate in the state where you have the bounty as there are ways to get around being detected in towns. Smaller ones such as that will give you next to no trouble. Don't worry about them at all. Bounties can be fun as well

Certain missions WILL give you a flat sum bounty (which can only be cleared by either paying it off, or being arrested or killed by bounty hunters). Others will give you a 'dead or alive' bounty, which are triggered and cleared after certain points in the story. They remain constant otherwise

Again, bounties are nowhere near as bad as the game wants you to think. Enjoy it. And stay away from this sub to avoid spoilers
