Why is everybody making everything so personal in this sub-forum? Can't everybody just calm down, try to read the market and make money of the right decisions?
If you "read the market" correctly, you take money from someone else. If incorrect, someone takes money from you. This is why I don't really like commodity speculation; if you win it just means you're a coercive asshole
You also gotta remember that 100% of people on this board think they're smart enough to be on the 50% side who come out ahead. 50% of them will be wrong, and probably not be willing to admit in here on the forums.
The only way you can 100% make money is to have mined coins yourself, the older the better. Then you can sell to newer people at the bottom of the pyramid.
As a currency, bitcoin is just brilliant, revolutionary even, and I love to use it. As a commodity it has way too much in common with a Ponzi for me to touch it at this late point years after inception
