I'm new to this forum and I really love the idea of your project
Yes you have a platform but it hasn't been tested at any kind of scale yet and won't be until you have already taken in millions of dollars via your ICO and selling the in-game assets.
In terms of scaling they are switching to Ethereum soon, which should be able to handle most future transaction loads in terms of in-game asset trading especially once ETH switches to POS. They are temporarily on Counterparty, XCP, which wouldn't have scaled well as it runs on BTC. (Slow and high TX fees)
Because of the overload of the bitcoin network and the very high taxes we are currently technically challenged and in the impossibility of delivering full team packs.
We are now analyzing the options to find the easiest and most reasonable way to distribute the cards in order that people willing to buy the full team packs are not affected.
In the shortest possible time we will announce the new discounts and the new way of distributing the cards.
We're sorry for the inconvenience.
I am also unable to access my XFC I bought from a BTC address because the XCP wallet has sweeping problems which is annoying. However XFC is probably one of the most exciting investments in terms of potential upside imo.
..In conclusion, a sceptic might think that this is just a very well organised scam. You could have set up a really nice website, put together a business plan for an idea which is actually really good, paid for a subscription to OmniSport and got your logo on their website, and made a bunch of claims which can't really be proven until the start of the 2017/18 football season.
With regards to your other questions, they all seem to relate to transparency & more in depth information about the team involved. I think many of those questions are valid.
However there is clearly an enormous amount of work and money that has gone into the project so far in terms of website, wallet, platform and other development. So I'm personally satisfied it's very unlikely to be a scam.
