Basically, I hold crypto but exchanged them for the first time on change hero. I tried to get some Ethereum and sent my bitcoin to them. I was a bit nervous about why it took a while to convert and texted the support. They explained to me that it was due to the rush in the blockchain. I received them after a bit but it was not so tough as I thought. Support is helpful and gave me clear information. I can say that it is a good place to exchange crypto.
