WHAT IS BITCOIN?

Bitcoin is a type of digital currency in which encryption techniques are used to
regulate the generation of units of currency and verify the transfer of funds,
operating independently of a central bank. See weusecoins.com for more
information.


INFORMATION

Coinb.in is a free and open source project released under the MIT license,
originally by OutCast3k in 2013. Discussion of the project can be found at
bitcointalk.org during its early testing stages when its primary focus was to
develop a proof of concept multisig solution in javascript.

Coinb.in is run and funded by the generosity of others in terms of development
and hosting.


PRIVACY

Coinb.in believes strongly in privacy, not only do we support the use of TOR,
the site does not collect and store IP or transaction data via our servers nor
do we store your bitcoins private key. We do route traffic via cloudflare using
an SSL certificate.


SUPPORT

We recommend that you first check our service status page and then blog page
which has multiple guides. However if the problem persists you can contact us by
emailing support{at}coinb.in.
