Hey guys, I sent ETH from Coinbase to the escrow address provided and supplied my private BTC wallet address.
The transaction on coinbase shows confirmed with 52+ confirmations but in my NVO.io dashboard ETH next to my private contribution ETH address still shows 0.00 ETH.

What does this mean??? Any help will be much appreciated!
It takes 1 hour on average, but it can take longer. There is absolutely no need to concern yourself with numbers on the dashboard. Just stay calm and look tomorrow.
is it always like this that? i can't see the amount of BTC i transfered to the escrow address?
Yes, there is no BTC balance on the dashboard.
will i no receive my tokens on two addresses?
If you send from address A, then you get tokens on address A (for Bitcoin obviously). Optimally you'd only use 1 address to avoid having to keep safe multiple keys.
I participated in the NVO crowdsale sending btc using Electrum Wallet. The address that was used to send from is now erased ( Electrum does this and I did not realize before it was too late). This means that I do not longer control it. The tokens will therefore be sent to an address I do not have the private key to.
What do I do? Can I change recieving address?
No. Electrum does not delete anything, it merely *hides it*. Learn how to export the private key from Electrum (which is what you should have done before even investing).
