Is it possible to claim BCH without knowing private key?
I have some Bitcoins in CoinsBank account (https://coinsbank.com) topped up before the fork. CoinsBank officially declared that they will never support BCH, so I'm seeking for ways to claim it.
For example, what if I create a BTC wallet, send my bitcoins there, and then broadcast the same transaction in BCH network?
You can't claim BCH without knowing private key, even if you withdraw that Bitcoin to your BTC wallet. Because, it means that you will get Bitcoin into your wallet after BCH fork.
To claim BCH, you have to have Bitcoin on your wallet before BCH fork.
If you make a BTC transaction, it is not possible to broadcast the same transaction in BCH network manually. BCH uses "sighash_forkid" to distinguish, so BCH won't accept the transaction that you made and broadcasted to BTC network.

Why does bitcoin have miners? Why don't the users mine their own blocks. I understand it may be to ensure the currency is traded, but in any non transaction blockchain case do you need miners or is it fine to let the users mine their own blocks?
I couldn't find any reason as to why bitcoin really needs miners other than for adding coin to the market.
The only distinction between a user and a miner is that a miner is doing computational work to get bitcoin, and a user is using bitcoin to make transactions. A user could easily do the computational work as well, but then they would just be a miner. The reason not everyone is a miner is because not everyone wants to do computational work, many just want to make transactions.

I have been exploring bitcoin API and I found there is network fee for every transaction which is around 0.0001 but I noticed many trading and bitcoin related agencies doesn't charge any network fee at all for transfer between user on same Website/App. Few of which are cryptopia, Zebpay and localbitcoins.
Could someone help me understand that how they are able to transfer between wallet without any network fee.
Organizations that offer online wallets aren't obligated to handle transactions using the actual Bitcoin blockchain; they may instead choose to keep their own off-chain record of transactions between users. While faster and cheaper than on-chain transactions, this system is often less secure, especially since the transaction records are centralized.
Only when a user transfers Bitcoins between an external wallet would an organization utilize the blockchain; this is when a transfer would cost some network fee and take some time to process.

I am looking to transfer money via SEPA from one bank account to another - from an application.
The app needs to transfer funds in the name of the person whose bank account the funds are being transferred from - i.e. some third party gateway won't do.
Is there an industry standard/available API for doing this (I couldn't find one off Google)?
If not 1., are there specific bank accounts that allow API control?
Note: I read this SO article How can I electronically transfer money to another account using Bank Transfer (BACS) and my requirements are the same - i.e. registering a payee manually beforehand is acceptable.
Apparently Achta provides an API that connects to SEPA. See https://www.achta.com/Home/AchtaAPI

I'm student and i'm working on bachelor thesis. My app uses wcf and sql database. If I want to test the application I need to host it. I would like to host it on Azure, 90 free trial, but it needs verification with credit card. I'm worried about sharing my credit cards data. I want to ask you, if it's secure and after 90 I have to pay for it or not?
Thanks
The billing and credit card information is hosted and stored by Microsoft themselves — you can look into the security of their practices in detail, but I am sure that they are okay. As long as you delete your database before the 90 days is up, you won't need to pay anything. You can still keep your subscription, just make sure that you aren't using any services. For peace of mind, check your billing on a daily basis and make sure that nothing is being recorded as running.

I was going to write an online ordering system for a small deli, and was wondering what's involved in accepting plastic payments online.
Both the deli, and it's customers are in the U.S.
If the deli already takes credit cards, you should contact their credit card processor and see if they have a internet payment gateway (and library/API).
If not, you need a Merchant account at the bank and a Credit Card processor that provides the gateway and API.
Edit: Other options would also be to go with PayPal or Google Checkout integration.
