I will post in english, since I don't know how good the online translator actually is and maybe it's better to have ok-ish english than bad translated croatian.
So, as for the wCHI, you can buy additional SMC with it or packs directly. 1 pack costs 1 wCHI and gives you 100 shares in 5 random clubs (5x20). If you want shares from a specific club, you would have to go via the order book of that club and either accept sell orders that are already in the market or put up your own buy order and wait for it to get matched. In the order books you use SMC. You can also direct message users in the game, so if you see someone having lots of shares in a club and you would like to buy some shares from him, you can negotiate a deal/price and do it via the order book or by transferring the SMC/shares (this is not trustless though then).
Shares in clubs give you dividends twice a week on the matchdays. The more shares, the higher the amount of SMC you will get. So you will generate passive income and if your club does well - maybe promotes, wins the league or cup - the value of your shares should go up as well.
At the moment managers are appointed by majority vote from snailbrain, but this is not how it will be in full game. Every shareholder with 100+ shares can propose a manager. This proposal period is 24 hours and afterwards there is 3 days of voting.
Since this game is about real money, managers not only have to know their stuff on the field and financially, but they also must be trusted and reliable. Otherwise shareholders will get mad with him (if dividends are low and share value goes down) and sack him. So the beta can already be used to show your are good and reliable manager to maybe get a job in full game even without any shares - but it will be ultra hard, there are only 300 manager spots available^^
Then there are player shares. These are not bought with packs, but are all already available to buy in the order books of the players; 10,000,000 shares per player. With 10% of those shares you are able to propose an agent for that player, which most likely will be you yourself. Player agents get a wage (as do the managers of clubs) on top of the dividends they get for having shares in that player. The dividends are higher when your player is in starting line-up, scores or assists. So the agent will always look to a) have the best contract for his player and b) have him in starting line up. That is something he will have to negotiate with the manager of the club. If the manager refuses to put him in starting line up regularly, the agent can lower the morale of that player or request a transfer. Agents can also decide whether a contract gets renewed or not.
Soccerverse is directly linked to real world football. Lets say you already followed Haaland, when he was still playing for Salzburg, a young and upcoming super star. You could then buy shares in him and make yourself agent - and they will be really cheap. Haaland then became a star in Dortmund and ManCity and this will also reflect in Soccerverse. His rating will go up in the game, so will his wage, so will your dividends/wage and the share price will skyrocket as well. So, working as a scout in Soccerverse is what a lot of people are looking at. But you have to be well informed about real world football
There is way more to the game (and tbh I haven't it all figured out yet as well, especially the ingame economy), but to summarize, there are lots of different roles in Soccerverse: Managers, Agents, Traders, Hodlers, Scouts. It's a very social game, where all roles have to communicate with each other to max out the success for their clubs, players and with that their personal financial gains of course.
All dividends are paid in SMC and you can either re-invest them to build up a bigger position in the game or you can exchange the SMC for wCHI and then to ETH/BTC or whatever you like.
Currently the game is running on Polygon, but it's not yet decided if the full game will be on Polygon as well. I am not a big fan of Polygon too, lets see what the team decides.
Feel free to post any questions here (I will answer in english, if that is ok for you) and/or you can DM me in Discord or ask in the respective channels there.
