Question #1 - how often do you buy crypto with fiat?
Question #2 - how do you choose the platform? Are there any other criterions than the amount of fee? Security, speed of transaction, simplicity, friendly service?
Aren't you afraid that your personal data may be stolen or sell somehow?
#1. I often buy crypto with fiat.
#2. I use my local exchange to buy the crypto, so when the price of the coin can increase in a short time, I can sell it, and it's automatically converted into my local fiat. The amount of fee is not too big to compare to the profit I made because if we talk about a 0.25% fee, that is not too big. The security and all of your question are good for me because I trade on the local exchange which I know where the office so if something wrong I can contact somebody to help me to get them.
I always try to be careful from the thief, but I cannot get 100% secure because the thief will always search a way to steal the customer data. And if that is related to the exchange I used, then I should know that they can be trusted, so I don't have to worry about anything.
