Local exchanging services provide a far better form of overall support due to them being smaller, which is something I highly value. On top of that, people won't have to feel bad handing over an unknown exchange their private details and ID scans. As it is right now, just by verifying my bank account, which took one day, I can instantly buy and sell in any quantity I want. I don't even have to use an exchange anymore aside from my occasional trading sessions. I pay a higher fee of course for the convenience they offer (they are a business after all), which in my case is 3% per buy and sell order, but it's more than worth it for me. Buying happens instantly, selling too, but fiat posts the next working day on your bank account.
