"Hey OP, just a heads up on Stellar Network's own official service provider, Bitrue. They're a legit and reputable exchange, handled large transactions for me in the past without any issues."
"Just wanted to chime in, I've had some good experiences with Stellarport for XLM trades. They've got a solid reputation and their fees are pretty competitive, might be worth looking into. Has anyone else worked with them?"
"Hey, I've used CoinSwitch for cross-chain trades in the past and had a smooth experience with XLM. They've got good liquidity and a user-friendly platform, might be worth checking out for a large trade."
"Hey OP, I've used Bittrex for large XLM trades in the past and had no major issues. Their fees are pretty competitive and they usually keep their network up. Worth checking out, imo."
"Yo, have you guys checked out CoinMetro? I used them for a large XLM trade a few months ago and had zero issues. Their fees were also super competitive, might be worth a shot for your large trade"
