Hi,

I'm just writing this to describe a bug in the wallet as currently released (operating on testnet).

Since the Windows Xcoin wallet has no idea about coins that have been "parked" in Minex, it is possible to use the coins in the wallet (some or all of which may have already been parked) to make a deposit to MinexBank. The coins then show up in MinexBank and can all be parked (even if some of them may have already been parked).

DISCLAIMER: WHILE THE CONTENTS OF THIS POST SHOW HOW TO POTENTIALLY "CHEAT" THE MINEXBANK PARKING SYSTEM IT IS NOT MY INTENTION TO SHOW HOW TO CHEAT THE SYSTEM RATHER THE PURPOSE IS TO SHOW A LOOPHOLE THAT NEEDS TO BE CLOSED.

In other words there is no communication between the Windows Wallet/full node and the "bank" in terms of which coins have been parked.

Here is the process, step by step:

(1) Send all your MinexCoin to the address attached to MinexBank (after setting up as described in blog https://blog.minecoin.org/how-to-register-in-minexbank-8f371bf6e5b)

(2) "Park" all your coins

(3) Return to your windows wallet, and "send" all of your coins to yourself (the address used to set up MinexBank account).

(4) The coins from your windows wallet show up in MinexBank, ready to be parked (even though they're already parked).

(5) Park the "new" coins [again!]

(6) Go back to the Windows wallet and repeat the process again... 2, 3, 4, however many times.

I would like to see this bug fixed, I have tried to report this on Telegram but I'm getting responses from the support indicating that this shouldn't be happening. I agree that it shouldn't be happening, but unfortunately it is!

Until the wallet/node knows that the coins have been parked they will always be available for sending. Somehow this needs to be addressed.

Thanks, hope you can help with this.

Rob

Hello, Rob!

1.When you registering in the Minexbank, you can tie one address to this account and you can see the balance only this address.
In the wallet, you can generate more number of addresses, that is, it will show you the overall balance of all addresses.

2.Here original instruction

How to participate in public testing?
Download the wallet. (https://drive.google.com/file/d/0B1dlB9NaqPEEV2Jmd1hLdE5CZWM/view)
2. Register in MinexBank (https://blog.minecoin.org/how-to-register-in-minexbank-8f371bf6e5b).
(https://www.youtube.com/watch?v=oXXGwl-4AA8)
3. Join the official group of MinexBank in the Telegram, inform us about your desire to participate in the test and specify your Minexcoin address in a personal message. After that you will be credited 5 test coins.
4. Park these coins and get interest.
5. Those participants who will create more than 10 parking lots before June 27, 2017, will be credited another 45 test coins.
6. Please note that the interest rate for parking will change during the test. Monitor interest rate changes and park coins more profitably.
7. If you see that the rate has increased significantly compared to the parking that you have already created, you can cancel the existing parking lot and park coins with greater profit.

okay, I was being an apologist for Minecoin but this response from the dev makes me feel like they have completely missed the point of what Rob was saying.... Rob already used the parking system, found a bug in it that exploits the parking payment, and the dev's response was like a copy+paste from another post which in now way acknowledged the exploit that was raised by Rob. @MineCoin.org did you not understand what Rob said? Are you really the dev or just their Public Relations person handling online interactions on behalf of the devs?

@Minecoin.org. Listen to Rob and get the bug fixed. I could sense some people already could cheat the system and get free mine coins from interest earned when the test is over. It could pose huge problems down the road and ruin the stability of this coin.
