1, so if I want to invest with ethereum as well, you will send the NVOT to the bitcoin address you got the BTC from (not the one registered), AND to the BTC address registered when I send ETH to the ethereum address generated?
You are confusing myself and yourself. If you invest BTC, it goes to the address that you've invested from. If you invest Altcoins, it goes to the address that you've put into the dashboard. End of story.
2, can I send ether multiple times from different addresses (to the one generated after I register my BTC address), so the NVOT received on the registered BTC address will be equal to the sum of received funds on that ethereum address?
Yes.
3, how are the NVOT shares calculated? does it matter when I send the funds, or are they equally calculated based on the current market price at the end of the crowd funding? e.g. when someone sends 1 BTC at the price of 2900$ and someone else sends a 1 BTC during the price of 2300$, will both get the same amount of NVOT?
Price at a fixed time after the crowdsale has ended.
I can send altcoins from an exchange correct? just not bitcoin?
Correct.
If the (lead) dev mix up hashing with encrypting that doesn't look good at all.
The condescending answer to a very legit question was uncalled for, since we are all potential customers.
Pure bullshit. Nemgun is not the "(lead) dev" and it's very normal to mix up terms under these stressful conditions. Stop trying to spread unnecessary fear.
