Credit cards, like probably everything in this world, have pros and cons. The biggest advantage is, for sure, the comfort which they give you. [<- perhaps better without the commas.] The comfort of not looking at cents or other “tails” of your final sum. Unfortunately, there are many more disadvantages. The first one is that every time you use it the bank earns (like) 1-2 % of your transaction, which should be in your seller's account but it isn’t. The second thing is that people with credit cards spend more money than with cash because they don’t see how their money is spent. And the third one, the scariest: you actually don’t have this money in your pocket(?) but in a bank account. It means that the bank or government can freeze your money and not allow you to use it even though it’s yours! It already happened in Canada during covid restriction protests. I hope that it never happens in my country but from that time I always have some cash as a backup.
