Ok, I was using the Bipcoin v.0004 from 1/16/2017. It looks like the 5/21/2017 version with the security fix doesn't have the start_mining in simplewallet.
 
Did you try calling miner from the command prompt? It looks like you tried to call it from within simplewallet since you got that "unknown command" error.
miner --daemon-address 127.0.0.1:18871  --address [WALLET_ADDRESS]
which is the same as
miner.exe --daemon-address 127.0.0.1:18871  --address [WALLET_ADDRESS]

My explanation does work to mine the most current version of BipCoin and I am currently solo mining with it.

I assume you are using forknote instead. The mining instructions for forknote are here: http://forknote.net/guides/#mining-with-miner

The command looks like:
miner --daemon-address 127.0.0.1:[DAEMON_RPC_PORT]  --address [WALLET_ADDRESS]
miner --daemon-address 127.0.0.1:18871  --address [WALLET_ADDRESS]

Let me know if that works for you!

Open your wallet in simplewallet. Then run the command start_mining or start_mining 2 (for 2 CPU threads). This will start you solo mining. If you check your system's CPU usage you will see that it is running.

I was able to get it working also but I had to switch back and forth between forknote 2.1.1 and forknote 2.1.2 to get the whole blockchain to download.

I'm having a problem with using the coin after the fork as well.

I am running forknote 2.1.2  withe the most recent config file and it can download the whole blockchain but when I try to open an old wallet it gets stuck scanning at block # 335928. I can create a new wallet and it scans fine but how do I open my old wallet on the new forked blockchain?

Your response does not contain any information that would contradict the assertion that BCN was mined secretly in a dishonest non-transparent way. Your response raises alot of questions and lists alot of example of things that you say are unknown or unproven but it is short on answers to the questions or additional knowledge or context. Certainly people who are associated with various projects that you mentioned know what the connections are between the projects but you falsely claim that this information can't be known by anyone. The claim that information is not known to you is not proof that the information does not exist.

BCN_official, Can you please respond to the allegations that BCN was not created in a honest and transparent way like other CyptoNote coin such as XMR and KRB? And that a vast majority of all the BCN are controlled by a small number of people?

I bet his CPU has 4 cores, That's why he has the option to mine with 1, 2, 3 or 4!

The problem that pushes the difficulty so high is nicehash bots mining at a profit when the difficulty gets too low.  The solution to stop them is to under cut them by buying nicehash mining at a lower profit and therefore being less disruptive to the block times. That is the only way to stop them from disrupting the blockchain because it effectively gets rid of their financial incentive to create the disruption.

If someone wants to put some BTC in a nicehash.com account and give me their API Key I can run my bot to keep the networking going fast. It will keep the blocktime under 1 hour. https://github.com/KittyCatTech/bipcoin-nicehash-bot

The only problem is right now you will pay 0.00001967 BTC per BIP mined to buy the hashing power on nicehash.

If you like the Bytecoin & CryptoNote technology, you should own the Bytecoin clone KRB (Karbo) rather than BCN.  It has better devs and is making faster progress toward usability then Bytecoin. Read their Roadmap at http://karbovanets.org/info  It has been going up in value much faster than any other CryptoNote coin recently because of the progress. https://coinmarketcap.com/currencies/karbowanec/  KRB has an honest and devoted team. You will find much better support, community and usability with KRB.

If you want to buy 100k BIP at 0.00001000 you can do so now on Cryptopia.

As I mentioned before the updated BipCoin Nicehash Bot is now working. I just made the update available on github:
https://github.com/KittyCatTech/bipcoin-nicehash-bot

Please help me keep the BipCoin block times stable by running the bot when you have some BTC to put toward mining BipCoin.

If you would like me to run the bot on my server for you and point it at your nicehash account to update your nicehash orders. Please DM me with your Nicehah API Key and I will get you set up.

I'm happy to report that BipCoin blocktimes can now be kept stable and ready for fast transactions. The price of BIP is already on the way up.
Let's keep making dark coins fun again!

I have sent the node list twice and have had 3 different tickets closed with no help. They have had no connection to the BIP blockchain for over 1 week now.

Great! Thanks for the encouragement, I'm glad you are happy with the difficulty finally being stable again.

The price in USD has been staying between $0.02 and $0.06 for a while now. As the price increases I am going to try to stabilize that also so that there are not so many spikes and drops and we can keep it at a steady increase.

This is a good time to start buying a little bit of BIP each month.

The BipCoin block times are now being kept stable.  If you are interested in mining BIP and would like to provide some redundancy for the blocktime/difficulty stabilization bot I created that is now working please DM me.

This is very exciting for the usability and reliability of fast transactions on the BipCoin blockchain.

The username for the pool for each worker will be [address].[vardiff]
[vardiff] should be a number not a name. The optimal value for vardiff is 90 times the hashrate of the worker. i.e. 400000
 for a 4.4 kH/s worker.

Try username: 1Aiwe1sPZiGTCeev1QVFa3KNiMTkjRM6oz.400000 password: x

Please also consider mining BIP(BipCoin), it has often been one of the most profitable CryptoNight coins to mine.

I can help with automation scripts to check all the pools and exchanges to see which coins are currently more profitable to mine as their difficulties and prices change.
