Nice catch OP, and you also got the trace to a Binance address, I suppose you can contact Binance support and ask them to ban the account that owns the address, I think that possible.
I have been using the boomchange.com website for over a year. ~~
It’s legit and normal working platform. I have been using this website more than a year and I don’t understand why there were posted misleading reports. You can use boomchange free and its legit well working swapping service
And you both two newbies account just coming out of thin air defending the exchange without any proof is just raising the red flag higher for this exchange, at least if you actually want to defend the site, you need to also post some proof of your transactions.
