Is it possible to send BTC out of an exchange account, in order to bypass the private key management system

Is it possible to send BTC out of an exchange account, in order to bypass the private key management system

Inspired by this other question, I wanted to ask a question related to how the private keys are managed by the different exchanges.

The question is: do any of the exchanges allow the sending of bitcoins to external wallet addresses?

(My reason for asking this is that I was thinking it would allow the user to send bitcoins to an address controlled by himself and then get around the enforced private-key management system.)

What exactly is a block?

What exactly is a block? I am trying to understand the Blockchain algorithm used in Bitcoin. I do not get the part how blocks are created. Let’s say transactions occur at some time. Then, if some nodes get these transactions, these verify the transactions are valid and then send it to other nodes. With this verify-send algorithm, almost every node verifies these newly occurred transactions in few seconds. Now, it is a time for a miner to do his job, which I do not understand. He needs to find a nonce which makes a lower value than hash values given in transactions. Question 1 How many transactions should a miner should verify in a single block? For example, if a miner A finds a nonce which gives a lower value than hash values given in 50 transactions, and if a miner B finds a nonce which gives a lower value than hash values given in 70 transacations, would a reward be given only to the miner B? So should a miner appropriately choose how many transacations he will work for? Ques...

Firmware With Unlocked Overclock for Bitmain Antminer Z9 Equihash ASIC Miners

Firmware With Unlocked Overclock for Bitmain Antminer Z9 Equihash ASIC Miners It seems that just like with the newer Antminer Z9 Mini the new faster Antminer Z9 Equihash ASIC miners from Bitmain are arriving with locked overclock functionality in the firmware. We already know that these ASIC miners are overclocking pretty well and you can easily get a nice performance boost over the stock hashrate the devices come with, so why is Bitmain limiting you… it is pretty clear, they want you to buy more units. Fortunately there are alternatives that allow you to overclock your Antminer Z9 miners and get a nice extra performance boost. Initially there was only a modified firmware released by user efudd on Bitcointalk that was sold to interested people, but now there is also a free version of a modified firmware available with unlocked frequencies by smartass111. Of course you are more than welcome to make a donation to the author of the modified firmware in order to support and motivate him....
