hello, using counterparty what does it mean if i have an electrum wallet to send btc from? is compatible?
You can send from any wallet which is allowing access to private keys. They meant you should not send from coinbase nor xapo kind of web wallets as they are not allowing us to access the private key of your bitcoin addy.
how could i see my nvo tokens?
To see NVO tokens you might need to import your privatekey into NVO's wallet (probably after moving out any of your BTC balances, if you concern). NVO wallet yet to be released and token distribution is not happening now, hence you cannot see right now. You need to wait till ICO ends.
