I paid a small amount on the IPO-Markets platform through a site called Aventigo in order to test its safety, correctness and professionalism.The consultant has repeatedly tried to make me invest shares of 10,000 euros in companies that produce components for batteries, such as lithium, etc… with various excuses I have always refused because I wanted to submit them to the withdrawal test. In fact, when it was time to withdraw, I did not receive any credits. All disappeared..so beware!!! FAR FROM IPO-MARKETS and these foreign telephone prefixes!!! If you come into contact with a foreign prefix it is most likely a scam!!!
