The Dashboard on NVO.IO doesn't track the Bitcoins deposits, it is not required because of the escrow address, anyone can check the state of its transaction on the blockchain directly.
The most important is not to send from wallet services like blockchain.info, coinmama or exchanges like poloniex, bittrex, or services like gambling. The bitcoins must be sent from the entered address on the dashboard, and this address have to be a private bitcoin address whom you own the private key.
Because you will receive the Tokens into the address you send from.
is it not enough to control the private key of the btc-address you put into the dashboard?
after the first funding i sent some BTC-dust more. but for this i used an other sending address.
will i no receive my tokens on two addresses?
