I guess if that link is a referral link that you want to share with us because I check on ftmo dot com, I see that they are almost similar to a trading broker, which offers their skills to people who want to trade.
I read on their ftmo.com/en/why-ftmo-challenge/ page, wherein I see "One-time fee only (no recurrent charges or other fees)," so I assume that we need to pay to use their services.
The subscription fee is about €155.00, which is too high. Besides that, the trade is for stock, not crypto, while we are in the crypto forum.
