Had to do an international transfer and it took a total of 20 days and didn't even go through, used ERC20 USDT and it took 15 minutes

So just like the title says. I was paying for something that accepts FIAT and USDT and I decided to use fiat money instead of their option to just send ERC20 USDT. I thought you know "lets just do it the normal way as I just have to add some info and thats it" WRONG.

I added all the info but I missed one little instruction since it was an international transfer and it used an intermediary bank. Paid 3% to send the amount and 5 days later the recipient hadn't received it yet.

I called the bank, which in turn helped me recall the payment. But GUESS WHAT?? yeah, they didn't actually recalled it so I had to call again to verify if they actually recalled it, bear in mind that I did this cause I was paranoid as it was a good amount of money, they told me they hadn't recalled it and they would do it later. I told them that I wasn't going to wait and to do it right there, apparently I was mad enough cause she actually did it.

Around 15 days later I got my money back with 3% less off-course as that was the fee I lost for doing the transaction in the first place.

Right there and then (as soon as I was sure my fiat was back in my account) I decided to do the ERC20 USDT option and I timed it, even with swapping ETH to USDT and then sending and them receiving it all took 15 minutes.

I just want to say that who ever is thinking crypto doesn't have the potential to move the world is just not looking at the shitshow their centralized system is, we can do better and this is the answer to that.
