During ICO total amount of XEL was sold. there will be no inflation!
This total amount was initially 5 million but after voting of token holders it was multiple by 20 and now 100 million.
ICO funding was about 600-700 BTC. Dunno the exact amount and too lazy to search

Again this number is useless, because we will have a final product at launch in contract to many other ICOs.
Total of
708.66 btc was collected. I agree, considering this project is a
final product, it will be just not fair if it costs lower than our competitor Golem with it's 22m$ marketcap.
And speaking honestly I see Elastic at 50m$ marketcap and higher. So one must be crazy to start selling his XELs lower than 0.22$ per XEL (or 0.0002btc at ~1100$/btc), just my thoughts..
