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..
These coins have small circle of people. First there will be small exchange, on which will sell those who need to get out of this asset. The rising cost of Bitcoin may adversely affect XEL price.
