Changenow.io is a scam exchange with fake team if you read here: https://bitcointalksearch.org/topic/changenowio-evercode-lab-scam-illegally-holding-of-100-bch-11-bitcoins-4619534 .
Now that I have checked your last posts you made, it seems like you are likely a shill account going on promoting changenow here and there.
I think it will be nice to use an exchange that uses KYC for a large 10 btc transaction because of the amount, security guide is important. You never would say who is trying to hack your account.
I don't usually send feedbacks for spamming of these kind. But next time when you post take care of what you are vouching for.
Feel free to take it or ignore it.
