United Kingdom
General community for news/discussion in the UK.
Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.
Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.
Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.
Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.
If you think "reputable news source" needs some definition, by all means start a meta thread.
Posts should be manually submitted, not by bot. Link titles should not be editorialised.
Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

Basically you have a bitcoin account. That account has a username and a password. You can share the username to have people send money to your account. However you can only send money yourself if you know the password to the account. He had his only copy of the password on the hard drive. So if you make two copies of one, you just have two copies of the password to the same account.
What's so special about it is that it's not centralised. With maths you can generate a declaration using your password to attach to your username saying you are sending money and that everyone should update their records. These cannot be faked without a password.
A lot of cryptography and maths goes into it. And the passwords are long strings of random letters and numbers that you cannot choose, same with the username.
