I've been playing ultimate team now since it was released on fifa 10, this post will be full of useful information including money making, good investments and squad/team tips.

Amatuer - 2/10k coins
One of the most basic but most successful way of earning coins is by trading, at this stage you can pick up gold contracts for 150 coins. The way i like to do it is by going to the market and put maximum price as 150, then just bid on as many as i can for 150, you will win a few of these as they may not be displayed on everyones market. This technique can also be used with players in the same way, I've been making about 10k an hour using these, I hope they help you.

Semi Pro - 10/30k coins
This section is basically about investing in players that are now worth around about 2-10k but will 100% double price or maybe even triple when the game is released, I will try name as many as i can off the top of my head...
El Kabir,Ramires, Walker, Ba, David Luiz, Wallcott, Lennon, Smalling.

Profesional - 50/100k coins
Nearly all decent players will double in price when the game is released so I advise anyone who has a high ammount of coins to start spending it and bringing in top players for example Rooney, Tevez, Aguero and Van Persie.

Team Tips:
This is just my opionion but I think these leagues would make the strongest team this early in the game.
Barclays Prem
Liga BBVA
Bundesliga
Serie A

Ea Sports Season Ticket
I strongly advise if your looking to make a good team that you buy the season ticket as it allows you to download the game 6 days before its released, you also get 24 free gold premium packs, 1 per week for 24 weeks which comes to a total of 1600 MSP anyway...
It costs 2000 MSP and can be found via BING search on your dashboard or just by searching in the stores.

Thanks for reading I hope this helped!
I'l keep you updated as soon as the web app's back up.[b]
