Hi I have lot of BTC to sell.
Can any experienced people guide me?
Thanks
proof?
post a screen or better a video that proves that you hold a looot of BTC

Why would anyone need to prove anything to you?
If you come here claiming you have a lot of Btc you should be ready to back up your words with facts to make people believe you or you will just be considered at best a boaster if not a scammer.
PS: by the way , are you an alt account of original poster? isn't it?
I don't have any BTC no. And if someone show ups somehere claiming he/she have something he/she doesn't need to back up anything? Or are you the police? I don't mean to be rude its a legit question. what is an alt account of original poster?
