Reasons why player cards can rise or fall

Announcements from Sorare
In February 2021, it was announced that Sorare had completed a $50m investment round. Accordingly, ticket prices increased exponentially before stabilising in April 2021. Increased media attention from additional rounds of Sorare funding or newly licensed teams and leagues on Sorare can cause the value of almost all player cards to increase rapidly and for an extended period of time.

Players in top form
In the best case, you have players in your squad who constantly score green, i.e. score more than 50 points. Check what the form curve is due to. Did a player have easy opponents or is he really improving steadily? If a player's form curve is due to easy opponents, there is a good chance that the player's card will lose value in the future.

Team building before a gameweek/game
Managers building their team for the upcoming gameweek may find that they need an extra man due to injury or simply want to strengthen their team.

Participation condition of the weekly special tournaments
The weekly special tournaments have their own rules, which reduces the number of participating managers. Managers must assemble a team that complies with these rules. The prizes in the weekly special tournaments are usually very generous and can cause a lot of excitement. If you have players who meet the special weekly rules, it may be time to sell the card.

Live performance of a player
If your player is performing very well and has just scored a goal, it might be worth selling him immediately. Other managers may have just become aware of him and want to buy him immediately for fear that the prices will rise too much.

End of season
Before a new season begins and the cards for the new season come on the market, there is usually a period of time when cards from previous seasons are sold slowly or not at all on the market for new cards. This means that cards become scarce and managers preparing for the new season are short of new player cards.
Before the cards for the new season come onto the market, the value of the player cards from the previous season can increase again.
Selling in the period before a season ends and the cards for the new year are released can be a good time to profit.

Cryptocurrency ETH
Player cards are bought in the cryptocurrency Ethereum. So if you successfully auction a card for 1 ETH today and the currency ETH doubles tomorrow, the amount in fiat you originally sold the card for will arrive in your wallet.
