Will everything be converted to BTC at the time of deposit?
We'll be accepting Bitcoin, Ethereum (ETH) and Lisk. All the funds will be kept the same way as we receive them.
At the end of ICO, that is on 29th September at 20.00 CET we'll calculate value of investments in EUR and you will then you will know fixed number of ICN tokens.
The same will apply to USD deposits.
Currencies that will be accepted via Shapeshift will be converted to BTC at the time of sending them and kept in BTC>
In this case the less volatile option to deposit is EUR, right ?
If you don't poses any crypto now then I would say yes.
And if you compare usd/eur then eur is the one that is not volatile. But USD can be compared to eur.
I think even if you have crypto, because you mention "At the end of ICO, that is on 29th September at 20.00 CET we'll calculate value of investments in EUR and you will then you will know fixed number of ICN tokens", because you are going to use EUR as your functional ICO currency, the only way to avoid value fluctuation (in your favor or against you) is to convert any other currency (crypto or fiat) in EUR and then deposit.
Don't you agree ?
