How much do you think a broker should charge for buy bitcoin?

I think they should make somewhat of a profit but shouldn't overprice people there has been many times where a broker has tried to charge an outrageous fee but i just wanted to know everyone's opinion on it

Here's a list of some brokers and there's there's some that are 0.02% which is really fair but I haven't tried them out on how legit they are

Alway's remember to buy with caution from sites.

But I use to use Coinbase but the fees were a little too high for me (at 1% fee) and I found another site that was a lot cheaper (Can't remember what it was as this was a few years ago)
