Not going to lie I'm still a bit skeptical of Novaexchange, but everyone is saying that it's working so I'll take your guy's word for it. For the sake of not scaring people off because of Nova we really should get listed somewhere else. No rush, but the dude talking about Bittrex around the 20th airdrop for better distribution is on to something.
I did my first purchase on novaexchange.com with no issues, I then transferred onions out to my new onion wallet. I recommend novaexchange from my personal experience I had today.
I cannot count how many times I have traded with NovaExchange, I cannot count how many BTC worth of coins have come in and out my NovaExchange account, and yes I have NO trouble ever in moving my coins in and out. DeepOnion in NovaExchange, just like other coins, for as long as the wallet is online, should have no problem depositing or withdrawing.
NovaExchange may be a small exchange, but it is working good. If there are issues, they are worked out until resolved. So in conclusion, I trust NovaExchange. Among the 150 or so exchanges existing, Nova is my 4th most trusted exchange site.
