.&&&.&&&&. ..&..&.&.&
&&..&&...& bitcoin is a crypto coin, crypto here ..&&.&&&&&
..&.&.&..& meaning "hidden", because this money is &.&.&&....
..&&&&&&.& invisible, intangible (yet still real)! .&&&&.&...
..&.....&& this is a symptom of it only living on &&...&&&..
..&&....&. the internet - in fact, if you were to ..&..&..&.
..&.&...&& remove a bitcoin from the mainframe, it ..&&.&&.&&
&.&&&&..&. would immediately die and become &.&.&&.&&.
&&&...&.&& worthless. .&&&&.&&.&
...&..&&&. &&...&&.&&
&..&&.&..& it works like this: if you make your ..&..&.&&.
&&.&.&&&.& computer create a lot of heat, it's &.&&.&&&.&
..&&&&..&& rewarded with bitcoin, as a token of &&&.&&..&&
&.&...&.&. gratitude from time's arrow. ...&&.&.&.
&&&&..&&&& ...&.&&&&&
....&.&... then every other computer has to sign a &..&&&....
....&&&&.. document stating that those coins are &&.&..&...
....&...&. actually yours. you can then send them &.&&&.&&..
....&&..&& to others, generating a new document &&&..&&.&.
....&.&.&. for everyone to sign. &..&.&.&&&
&...&&&&&& &&.&&&&&..
&&..&..... and because you're knee deep now, you ..&&....&.
&.&.&&.... have to sign a lot of documents ..&.&...&&
.&&&&.&... yourself, and keep track of who signed ..&&&&..&.
.&...&&&.. what, and look for forged signatures, &.&...&.&&
&&&..&..&. and probably forge a few yourself... &&&&..&&&.
&..&.&&.&& &...&.&..&
.&.&&&.&&. also, in the end it doesn't work. &&..&&&&.&
