Besides using it as a currency it seems like its impossible to make money off of bitcoins unless you already have some serious cash , mining bitcoins is long done nd over with nd its seems like trading/exchange doesnt give you much of a profit , so im just wonding as someone just now arriving to this dead party whats there to do with bitcoin ?
I think your right about much of this. Bitcoin never was more than money. It's the best money, but just money. So what can you do with it? Anything you can do with the other money you have and lots more. The real power of bitcoin is not well understood until you know a lot about money in general. Fiat money or private money systems have inherent problems starting with trust. For example if you have dollars in your pocket those are not actually yours, they belong to the federal reserve. The issuer can change the value as they wish, the supply, the distribution. You and any wealth you have stored are just along for the ride. Bitcoin is open source, peer-to-peer and beyond the control of any authority. There is only the market and the 100% predictable math used in it's operation. You can trade with your neighbor or someone on the other side of the planet. No other money in history is like this.
