It is impulse buying and racking up credit card debt that are the enemy. They can be a great tool if used properly.
There are pros and cons to everything but it matters how you use it, just as anything can be weapon if you try hard enough.
There are a growing number of people that use credit cards as a side-hustle. Racking up rewards for buying things they were going to already. This can be a new washing machine, your vacation, etc.
For instance, last month, just using one credit card to buy things I already planned on. I made over $150.00.
Now, I agree that seems like a drop in the bucket. However, if you credit card churn for 12 months, it is $1800.00. It is income. All you would be doing is buying what you were already going to pay for, like bills and the like. As long as you pay it off every month, then it is free money.
