I'm very sorry for your loss, but you seem to have forgotten the rule - Do not send more money than you can lose, especially not to questionable exchange like this.
I did not understand, you deposited your BTC and ETH there? On your video, I see 0.37 BTC and 5.37 ETH. It's not 3BTC.
You have tons of Fitrova token which is inactive on CMC from Aug. 2018
https://coinmarketcap.com/currencies/fitrova/ is it really worth 1.5BTC?
p2pb2b is a proven scam exchange, but you can't expect from any exchange to refuse paid listing because of words from some internet person. Especially can't expect that from p2pb2b exchange.
i lost my life saving money to tagz exchange and p2pb2b listed tagz fake volume and scam exchange. i am going to report england and estonia authority about p2pb2b scam listing. hope if you see my thread help me to spread my voice to everyone.
p2pb2b England office is fake, so you don't waste your time. Probably Estonia also.
On the Tagz website, I can't find his office address or any live contact. They declare that is registered in
"Australia under Tagz Group Pty Ltd and Registered ACN 632 160 920". Also there probably on paid
Stemit post with fake comments.
So it's better to report them to Australian police to investigate the whole case. As far as I know, they are very azure.
you will need to provide all the information and transaction details. I hope you have it. Your correspondence with Coinmarketcap is totally irrelevant in this case.
