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.)

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password I used btcrecover to extract the wallet file (wallet.aes.json) from a blockchain account and I have been running btcrecover with dictionaries of my making but it has been going on for weeks and I am running out of ideas on how to permutate what my wife and I think the password could have been. Is there a way to just manually transfer the btc from the old wallet into a new wallet we do have access to or is there any way to extract the password or private keys directly from the wallet file? We have: the phone with the original wallet app installed, the wallet file pulled using btcrecover, access to the email to allow authorization to access, the wallet identifier that was sent to her email when she first signed up, the phone which has the wallet, the pin that was used for the wallet, and we know how much btc is in the account. We do not have: The pri...
