Coin control was not a feature of the original Slimcoin clone of Peercoin's clone of Bitcoin 0.6, it was backported later.

By default, the wallet will choose to collate a set of smaller transactions to make up the intended amount. The original clone is of Bitcoin 0.6 and at this early stage of the development of Bitcoin's codebase, this algorithm is very simple, it starts with the smallest tx values in order. As d5000 has already explained, the "Unable to send transactions" means that in order to make up the total you are trying to send, the wallet has to collate a number of transactions that exceeds the encoded limit. The solution is to gradually reduce the UTXO set by sending very small amounts at first, gradually increasing the amount.

Step one: close client, restart with -rescan=1 option. Wait until complete.

Step two: Try sending a small (e.g. 0.25) SLM to an address you control.

Stop here. Please report back on whether you can successfully send a tx of 0.25 SLM to yourself.

If successful, repeat with the amount x 2, continue until "Unable to Send Transaction", go back one step, continue to send that amount repeatedly until all your SLM are collated into a single address.

When I did this, I repeated the exercise, working my way down from my total balance until the tx succeeded.

You might care to back up your opinion by inspecting the source code: https://github.com/slimcoin-project/Slimcoin and identifying the likely cause of your difficulty.

Excellent news. Glad you now have full control.

I think some of your burnt coins are already decayed thus there is a difference between what's you originally burned and your net burnt coins balance.

If you are still experiencing the issues with the wallet you can try to add some RAM to your computer it helped me greatly once.

Another idea can be to switch to the previous version of Slimcoin wallet. Have you compiled by yourself or just got the binaries from github?

Hello

The problem is not in the burned coins but in the

Balance = 41.69 SLM (transactions = 75)
Report = 41.69 SLM (transactions = 75)
Coin Control Features = 0 SLM

I have 8GB of memory (more than enough for any currency).

Going back to a previous version is not going to work ... or else I will lose all the coins burned and some that are being confirmed.

And thanks for trying to help, but in my opinion it's from the version code, something is working less well in this version.

I'm just talking here, because I think slimcoin is an interesting currency and maybe try to help improve the code.

You are welcome! But were you able to solve or at least to improve the situation?

@emrgohff: For me that looks like that you've many inputs (from mining, staking, PoB minting etc.) in your wallet. Maybe to get an idea you could post the (approximate) number of incoming transactions you received, or how long you are PoB/PoS minting or mining already? (if this is too private you can send me a PM)

If this is the root of the problem, then you should try to consolidate the UTXOs. This means convert many transaction outputs into a few transactions sending them to yourself, which will make your wallet "cleaner" and your Slimcoin client will work faster. The easiest way should be to make a big transaction (as big as possible without the above error) to one of your own wallet addresses first and then use Coin Control to consolidate the rest. Can be a bit tedious but is unfortunately currently not possible automatically. If you need more instructions (don't know about your knowledge level regarding Bitcoin-based coins) simply post your questions.

@emrgohff

Do you have many transactions already done with that wallet (included PoB rewards)?

Maybe you can reduce the number of maxconnections.

Also changing server=1 into server=0 and listen=1 into listen=0 may help.

By the way your slimcoin.conf is partially in Portuguese, at least the last version you've published. I'm not sure slimcoin-qt is able to understand Portuguese  

Please let me know whether any of above suggestion has improved the situation.

What version of wallet-qt are you using?
How much RAM do you have on your computer?

@emrgohff please let us know if you've solved

Ergh ... missed my alert ... block explorer 'expired' ...

- https://chainz.cryptoid.info/gap/

Decided to keep gapcoin.club nodes running for now (or gapcoin will probably 'die') ...

The miner built into the wallet is not worth using anyway, it's quite slow.

you can use rieMiner for solo mining, or join a pool.

https://github.com/Pttn/rieMiner

OK that's useful then hopefully.

Anyone can just up vote Gapcoin here at coinfalcon: https://feedback.coinfalcon.com/coin-request/p/gapcoin-gap

Good news (I think)!

One of Gapcoin's original exchanges (Nova Exchange) which went on hiatus appears to be relaunching 3rd December 2018 ...

- https://novaexchange.com
- https://twitter.com/nova_exchange
- https://novaexchange.com/market/BTC_GAP/
- https://novaexchange.com/market/DOGE_GAP/

So, Gapcoin is still listed at nova exchange and will re-open for trading on Monday? Tread with caution + show your support !

I'll contact nova exchange to touch base and to get them to update the logo.

...

Ongoing discussions with cryptopia regarding de-listing - actually talking to the relevant folks thanks to a bitcointalk forum contact.

"Their delisting policy is outlined here:
https://support.cryptopia.co.nz/csm?id=kb_article&sys_id=b8aa010ddb452b80d7e096888a961934

The following criteria are required to be met by coin projects at the time of the listing:
 
Active and visible development team with at least two contacts given to Cryptopia (Lead Developer and CEO or Marketing Representative).
Public and safe source code as defined by our code review.
A functioning block explorer.
Detailed whitepaper outlining the use case of the project.
Road map with milestones, preferably with some achieved.
A working and detailed website.
Is NOT a "financial product", under New Zealand law.
Positive community engagement within launch forum or similar social media spaces."

...

"Their listing policy is outlined here:
https://support.cryptopia.co.nz/csm?id=kb_article&sys_id=5d7482d2db9e9bc032a664a14a96199f

Be aware of our delisting policy and your ongoing obligations
Before you list, be aware of your obligations to us to help maintain your listing.

You need to give us notice of the following:

At least 2 weeks' notice of any significant code or protocol changes for your coin, especially hard forks.
Major issues with your coin, including hacks or network problems, as soon as you become aware of them.
Any issues with deposits or withdrawals of your coin from Cryptopia.
At least 1 month's notice if you want our assistance with an air drop. Be aware that support for this is solely at our discretion.
As much notice as possible if you need to conduct a coin swap. By default we don't support coin swaps, but they may be considered on a case by case basis.
Cryptopia reserves the right to remove any coin listed in its exchange markets for violations of our listing terms. This is solely at our discretion. Reasons a coin may be eligible for delisting include, but are not limited to:

Any network issues or vulnerabilities that could be exploited. Examples include:
Low hash-rate.
Out of date code base or wallet stability issues.
Frequent issues with deposits or withdrawals (outside of Cryptopia's control).
Insufficient nodes to keep the wallet synced and network propagating transactions.
Coins which violate our terms and conditions, policies, or an applicable NZ law or regulation
Coin swaps (where we are unable to support these)
Coins without a working, reliable block explorer
Coins that fail to provide notification of mandatory updates
Abuse directed by a coin team's core community at Cryptopia or its staff."


So, it is quite clear which criteria Gapcoin does not (only now?) fulfil in regards to the above.

Some aspects can be easily rectified, other factors, like the sudden miraculous production of a 'white paper' are perhaps less solvable in the short term over an updated wallet release (for added security). Anyhow, this is where we are currently at and I'm optimistic that we might get some workable extension through friendly discussion.

...

We need to maintain a position / listing on coinmarketcap.com (Note: nova exchange should re-list with coinmarketcap after the 3rd!?)...

Herewith, twitter .com/ handles for almost all linked exchanges... which could feature Gapcoin trading with increased community support and new development etc., ...
