You should download (via torrent) bootstrap.dat and put it in the Bitcoin data directory (usually C:\Users\username\AppData\Roaming\Bitcoin). Then start up Bitcoin Core and it will read the blockchain from there.

Well you dont put the torrent in that directory (which is only correct if you use windows anyway). You open it with your favorit bittorrent tool and put the bootstrap.dat in the that directory. Make sure bitcoin is not running when you copy it there and start normally. It will not download the complete blockchain but a big part of it.
You can also use another client like electrum or multibit that does not need the whole blockchain. They setup in a few minutes and are ready to go.

Pywallet is a tool. Its not like there are several pywallets.

No.
You don't need a special calculator for cloudmining. You can use https://bitcoinwisdom.com/bitcoin/calculator and enter the maintenance fee of the cloudmining service.

IMO, it is better to just buy and hold bitcoin.

The bottleneck with synching is not your CPU but your bandwith. You can however speed up the starting proccess by lowering checkblocks from 288 to e.g. 100 or even 10.

It's Bytecoin (BCN). They claim to have been around "on the dark web" for two years and then suddenly launched forth into the light in March (with 82% of the coins already mined). I went into a fair amount of detail as to why I think we should dispute their 2 year claim in this thread.

Incidentally, we forked BCN and create Monero a while back, which is based on the same CryptoNote protocol, but obviously has a blockchain that has had many observers from launch (and is already diverging from BCN's reference implementation as we rapidly improve it).

Chat is a matter of taste. For bank transfers you can leave a message, as well, so it would be useful to link the message more closely with the payment.
I think Bitcoin wallets could in general use a better design and this looks good to me!

Register in www.coinbase.com, they support email and message. you will get code in  mobile message,  after login and you need to put that code to access your account.

BTC moves too quick for real arbitrage (e.g. buy BTC on BTC-E, sell on Bitstamp, withdraw fiat and re-deposit on BTC-E). But since the spread narrows and widens, you can take advantage by, for instance, buying on BTC-E, selling on Bitstamp, and waiting for the spread to close before buying and sending back to BTC-E.

Sorry, just a quick reply (got to run...), there is a sample .conf file on the same wiki page. Did you have look? You can edit it using notepad for example.

Every line with a # will be ignored. Lines without # will be processed.

Also, as mentioned before, what are you trying to achieve?

You can use those in Windows via the conf file: https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File

It is kind of weird that they haven't even acknowledged that there is a problem.  Usually they address it publicly right away. I can get to Blockchain.info but not their blog. That website doesn't even connect...
