This would be the price without a bonus, which is what the white paper says is the base price. "The base price of IXT is 1,125 per ETH"
1 ETH divided by 1,125 IXT (0% bonus) = 0.00088888888
I think the way to look at is that you received an extra 56% (presale) 36%, 20%, 15%, or 9% (sale shutdown before 9% bonus started) IXT tokens as per the white paper.
Almost 0.0009 ETH per IXT
That will be around 7,600 satoshis, am I right? Then a dump to 3,500 satoshis and then a looong pump to 35,000 satoshis.
I am not sure, but you might be correct.
Since IXT was sold for ETH the IXT/ETH value it was sold for during the crowdsale will remain the same. However the IXT to Satoshi/Bitcoin price will fluctuate as the ETH/BTC value changes. Its best to calculate the newly created token value against the token (in this case the IXT sale was in Ethereum) that the ICOsale/Crowdsale was priced in.
You can calculate the Satochi/Bitcoin value on a day by day calculation, which is probably what you have done.
I hope for the best IXT value in the exchanges in the short term and long term. As per other ICO's it will likely go up and have a pull back and then go up again. I cant suggest an investment strategy, as it is different for each person. I personally think that at least a portion of IXT should be held long term. All good ICO's achieve a much greater value on exchanges over time than their initial pop.
