Pico stock exchange was the first stock exchange I have ever come across. It is a Crypto to crypto investment platform and also trading platform, but deals more on investment, which was brought up with an unattractive interface that kills the spirit of motivation among users. I lost interest on trading here because before i can even register here, I will have to contact there support team before any form of Registration can be done. I messaged the customer support team but up till date I haven't received any response from them, this shows that the exchange is not willing to have users on it platform, and this also shows the level of irresponsibility of this exchange.
In your own interest, you can try to message the team if you will receive response from them but I will advice users to suspend any attempt of willing to make any form of deposits.
