After a long time there is a new Version for the Lending app.

I removed obsolete coins and added the new ones listed on the poloniex lending market.

Most important for most of you I removed the subscription option.
This option was initially there to give the MUE-Coin a push because I belive in this project and still do.
However over time I got the feeling that the initial barrier for using this app is to high, having an Bittrex and a Poloniex Account and also hold MUE on the Bittrex wallet might have scared many interested users away.
So I removed the need for holding MUE on a Bittrex account completely. With that gone a Bittrex connection is no longer necessary and the need to have a Bittrex account is also removed.
Since the subscription option was there to remove the need for MUE this subscription option got also obsolete and was removed in this new Version.

The new Version holds 2 Versions a Free and a One-Time-Payment Version.
The only difference is that the Free Version will show small Ads from time to time and is using a simplified lending logic.

New Version comming up

Unfortunaly there was a crash in the CLAM lending market.
As a result Poloniex is removing all Markets with low liquidity from the lending market.
https://medium.com/circle-trader/overview-of-btc-margin-lending-pool-losses-a2f0905aaa56
Version 4.1.7 is removing this markets from UI.
This will not affect current lends on these markets.
Version 4.1.7 will be mandatory starting with 30. June 2019.

Poloniex has also decided to cover the losses via the BTC lending pool so everyone who had active BTC lends did lose 16.202% from the lends.
For Testing and Analysing Purposes I do hold a fair amount of BTC in my lending account to make updates and improvments to the tool.
I would be realy greatfull if at least some of you would donate to
BTC: 1C85CjZf5X2R3RW9R7B3AL3U2dsKaySacB
so that I can cover at least some of my losses and continue to work on that tool.

Version 4.1.6 is out with ATOM, BCHABC, BCHSV, EOS and ETC new in the list of lendable coins.

Hello,

I am Michael, Developer of the GoldfingerBank Lending Bot for Poloniex.
The application can be found in the Microsoft store and runs on Mobile Devices and PCs (https://www.microsoft.com/de-at/p/goldfinger-bank/9nblggh43vmj)
I use the application myself for 2 years with great success there is also a Facebook page where I pos current rates from time to time (https://www.facebook.com/GoldfingerBank).
The BitcoinTalk Thead is here (https://bitcointalk.org/index.php?topic=1684269.0)

The Application has a free version with a simple lending algorithm for testing.
There is also an addon which is free for the first 30 days to disable the need to have some MUE (1000USD) on your bittrex account.

Since the beginning I struggle with the usage data. That may be my own fault because I did not advertise the app pretty much.
Of course there are some strange behaviors in the application but nothing that can not be solved with a restart of the application.
To find and pinpoint the source of that behavior I need mor users that run into that behavior and can give feedback when this happens.
That is one reason why I bring you this offer.

If you choose to conatct me please give me 1-2 days to react.

My offer #1 is:
If you send me at least 0.2BTC I will send you 2 Promo Keys for the App to get the Full Version and the Addon as an Lifetime option for free.
All you have to do is send me a private message with information how I can contact you (I prefer Discord https://discord.gg/kJaGyc2). I speak english and german.
I will than contact you and answer any of your questions, bevore I send you the BTC address where you can send the coins.
I will also guide you throw the first setup process.

My offer #2 is:
I can also do the lendig stuff for you. For tems and conditions please contact me with a private message or on Discord (https://discord.gg/kJaGyc2)

Short Q/A
Q: Why you am doing this?
A: To promote my App a litte more aggresive.

Q: Why you am doing this, realy?
A: Long story short. I desperatly need money to pay some large bills to finish my house. I do not want to beg, so I want to give at least something in return.

Q: Will you accept coins as charity? I mean you need money right?
A: Yes, but I have a very bad feeling about that, and I waited till the very last moment to do that step. That's also the reason I am not spreading my BTC Address around and you have to contact me on a private channel. I want to get to know such generous people personaly and give them something back. Even repay them the money as soon as I am able to.

Sorry for the late answer.

This tool will continually alter the wallet settings too consider rising or falling dificulty and optimize the inputs in your wallet so that you stake more often.
The tool has an "learning" phase where it needs to adapt to your inputs and wallet settings (roughly a week).

I use the tool myself on a daylie basis and I do belive it rises my stake rewards at least for 50%. This is of course only a subjective number since I do not have any numbers to prove that.

Name: StakeMaster
Version: 1.1
Source Location: https://github.com/swtrse/StakeMaster
Binary Release: https://github.com/swtrse/StakeMaster/releases

Prerequisites:
dotnet core 2.1

The tool runs on Windows, Linux and Mac OS bases systems and other systems as long as dotnet core 2.1 is available.

The tool was written to organize staking wallets.
It is basically the implementation of the way I used to manage by wallets manually in the past.

Detailed description is available in the readme (https://github.com/swtrse/StakeMaster/blob/master/README.md)

Since Poloniex is closing the margin and lending market for US-based customers Goldfinger Bank will add an other excange without these limitations to it's portfolio.
You now you have the chance to vote for one ore more exchanges in the replies.
The exchange with most votes will be added.
Other exchanges will be considered to be added in the future.

Version 4.1.3 is out.

This one get rid of an anoying skimming bug where ever time you got skimming reward the new coin balance was not calculated correctly and an error occured.

I also addressed the problem that sometimes rates drops to a unusual low value.
Someone could use that knowledge to dump lending rates and the bot would follow the new low.
The new algorithm will only follow rate drops over a longer time period.

Skimming now also is only active when the available coins are at least 20 times the minimum lending amount for that currency.

Also new anual rates are reported on the Goldfinger Bank facebook page. Since we reaching the end of the year these predicted values get more and more accurate.

Since I am only occasionally at this forum and regulary on facebook there is now a facebook page for this app.

Version 4.1.1 will hit the Store 30.06.2018

There are some minor improvements most of them for the case where you want to enter you exchange keys and secrets and have to switch to a different app on an mobile device.

2 new Versions are comming addressing features that are most wanted.

4.0.4 is already available at the store. However WIndows phones will most likeley not get this version becaus of there OS version.
4.0.9 will be hit the store on 30.4.2018 so get your phone ready till that date the minimum requirement is the Anniversary Update.

Sorry for the late answer. I was occupied elsewhere
What you have to do is
1) Hold your MUE at least worth $1000 on the Bittrex account.
2) Move the coins you want to lend to poloniex and add them to the lending market.
3) Start the app register the api keys and start lending.
4) If you like the app invest the €4.99 to change to the full version witch uses an more sophisticated lending algoritm
5) If you do not have enouth MUE or want to try the app there is a subscription addon that deactivates the mue prerequesit. The first month is for free just not forget to unsubscribe if you do not want to continue or saved enougth mue to use the app without the subscription.

Finaly a new Version have arrives.
I addresses much of the flaws in the old version, especially the stability and some UI shortcommings.
I hope you like it.

As promissed here are the screens. Since BTC and ETC are my testing coins during development I Reset them regularly (That means Starting Balance and Revenue calculatet only by the last few days). All other Coins are running since 1.1. and since there is late in the year the calculated % is more accurate on this coins ^^.

Just for reminding the Annual Rate (Jahreszins) is calculated (((CurrentBalance-BalanceAtStart)/DaysSinceStart)*365)/BalanceAtStart
the only day when this is not a prediced value is the last day of the year

and I have skimming system activated witch moves 0.25 Pieces of a coin to exchange market after the balance grow a whole coin

Pool fee is changed to 0%. Only the 0.2% support for MUE foundation remains.

Of course I can. I will put some Screens here.
Currently there is a new Version coming v3.0.
With Plugin support
Currently there are 2 Plugins available
 Plugin 1: Will disable the need to hold MUE and use an Bittrex account for 30 days
 Plugin 2: Will disable the need to hold MUE and use an Bittrex account forever

As soon as I have the Version hit the Store I will make new Screenshots and post it here. Should be ~7 working days from now.
Currenlty earings are for Example: CLAM 11.8% DASH 1.2% LTC 1.7% STR 22.1% ETH 0.02%. I will provide Screen for each Coin soon, there is no reason to hide it

Thanks for your support.

There are some minor updates planed but I consider the project as finished.

Of course I will continue to fix bugs and update the api implementation if necessary.
I will try to make the next screen shots in English.
The app is multilingual (only German and English for know)

The new version is already in the stores. What makes it different is that the App is more stable know. I changed the way the application is working in the background completely.
As a side effect the background task will run even if the application is closed. So you can now start the application and close the GUI. It is more ore less a windows service and of course I could have implemented it that way. But I wanted to experiment with .Net Core and Windows Universal Apps.

This is no project of Poloniex. This is a tool written by me using the poloniex api.

It's done the pool is up again.

Not with the features I wanted to have, but at least up again and running  
I will have a closer look at the pool the next few days but all looks fine till now.
