Mr-Adalberto posted in last march 2019 about Labrotix from his account.
Labrotix: https://bitcointalksearch.org/topic/delete-5118440
He is the one claiming Masterwin is scam here in bitcointalk and in masterwin discord and claiming money. His discord account clearly shows he is from BLOCS project.
Just check Mr-Adalberto previous posts last year. You will see in how many projects he just posted scam projects and some messages he deleted the text. He has different accounts.
And these guys claim they are different not together.
And for gods sake yours is not stock exchange but crypto scam exchange.
Guys becareful about his exchange and BLOCS project. Its kind of a mafia they do on several projects.
As Mr-Adalberto is from Labrotix team here are some of his claims with different projects as scam. He might delete these soon so just taking screen shots.
