Common questions.
Why is it free?
It's the first season and we want you to try COTA90. You compete with virtual money and the prizes are real.
When does the competition start?
At 5,000 sign-ups. Until then, try the demo.
Am I investing real money?
No. You compete with virtual money. The prizes for the five best portfolios are real, subject to the terms.
Why does a player’s price change?
COTA90 compares what he did with what was expected of him. More than expected, up. Less, down. The match report explains it. That is why a Rayo player can rise more than a Madrid one: it depends on what was expected of him.
Can I buy players from different clubs?
Yes. From all of La Liga. Buy, sell and split your balance as you like.
