Interesting... so I think the difference for Hydranet (HDN) is this:

Hydranet works by:

1) Allowing users to move their assets from any supported chain (BTC and EVM chains [ETH, ARB, BSC, etc]) to the L2 equivalent for that chain (Lightning for BTC, and state channels for EVM).

2) Through an order book, HDN connects users directly to facilitate swapping of assets over L2, including cross-chain (IE, BTC on Lightning for say ETH in a state channel)
  2a) So if I had BTC and wanted ETH, I move my BTC to lightning, and then I am able to trustlessly swap my BTC on lightning for someone else's ETH in a state channel. This swap is a virtually free L2 transaction (compared to on-chain fees for BTC or ETH which can be substantial) and I only have to pay a small DEX fee. It is also being completed in SECONDS versus minutes for say Thorchain on-chain swaps

3) At all times I maintain custody of my assets. There are no wrapped assets involved, and I can move my L2 assets back to L1 whenever I want.

4) Bonus: I can also swap say USDT on ETH for USDT on ARB, provided I start by moving my ETH USDT to a L2 state channel, then swap as above. Completed in SECONDS for low cost, certainly orders of magnitude less than current bridging solutions.

Is my understanding correct? If so, this DEX is very different than any other solution out there. It's a CEX like experience with the order books, but is a DEX where you never have to give up control, no wrapped assets, and can act as a cheap bridging solution, and completes swaps quickly in seconds. Almost too good to be true, and if all the above is correct, seems like a game changer to me.

I purchased 3 coupons a few days ago - received instant delivery, and was able to redeem the first one without issue today.

Received - thanks for the support -all is well!

Purchased a Windows 10 Enterprise 2015 LTSB Multiple Activation Key from the Selly site. Key arrived ok, but the download link was broken (and also appeared to be a link to the wrong ISO). Messaged Azzazel through Selly, but also posting here as a follow-up. I'll share the final outcome once resolved.

Update: All hope is not lost. Finally received a reply after the web site went down last month, and did get my BTC returned thankfully.

Great point about people with small balances... lots of folks are going to lose out here

Still cannot receive the confirmation email and now this....

"Cryptostocks will seize its service on 30.04.2017

The platform will remain operational till that date. Please withdraw all your funds before the deadline. Withdrawals after 30.4.2017 are processed manually and will incur a fee of 0.1 BTC per transaction. Regarding questions about the securities, we ask you to contact the security issuer, they will be receiving all needed shareholder details. The website will be taken down on 1.6.2017"

I hope there is a window between April 30th and June 1st where a manual withdrawal will work - but I will be robbed of .1 BTC for this

Also curious to hear about the experience of trusted members... TIA

The problem continues - cannot receive the withdrawal confirmation email... in addition, one CANNOT turn off confirmation emails, as the system sends a confirmation to check that you want to disable that feature. Ugh!!! Save your BTC, stay AWAY!

I will reiterate again - even if the wallet is up, the confirmation email (required to complete a withdrawal) is down, making it impossible to get your BTC back. I have a pending withdrawal since March 28th that I cannot complete  STAY AWAY!

Just an update... still unable to receive withdrawal confirmation emails... still trying to withdraw. Request pending for months... STAY AWAY FROM HERE if you don't want to lose your BTC

I've been trying for months to withdraw my BTC... I can catch the wallet when it is online, but never get the verification email, so my request just hangs there. I did get email from cryptostocks when I signed up of course... I tend to agree with the scam warnings. My emails on this issue have gone unanswered
