Anyone who thinks they can figure out buy/sell signals for cryptos right now is a lunatic.
2. Shut the fuck up about "signals" and "trading"
3. Build cool apps around the crypto ecosystem
4. See more and more people using cryptocurrencies
5. profit
Example 2: I can utilize the blockchain to proof authenticity of a document, image, sound, will, legal document etc.
Example 3: Filecoin, Siacoin, Storj - P2P file hosting
Example 4: Aragon - Decentralized trust-less companies - Test their alpha version - it seems the solution on the governance of open source apps
Example 5: Decentralized exchanges - check etherdelta.
The above are just really basic examples - we are still in a really premature phase. The whole point of cryptocurrencies is that I can trust and exchange labor, money or whatever with anyone worldwide without me even knowing them.
The worldwide economic crashes were the result of people trusting 3rd parties such as banks, investment firms etc. This problem can be solved.
Even better, use the dollar cost average approach to buy and don't sell unless you are using it as a currency. The world needs a digital currency now but the volatility is preventing that from happening.
EDIT: The pair in the image is ETH/EUR
A normal stock has the underlying company, earnings, performance, forecasts, etc. to sort through and figure out where it is headed, but ETH and BTC have no such thing. So what better way to analyze than TA?
EDIT: bitfinex doesn't work on the machine I'm using. Guess shorting will have to wait for later.
Another way of shorting is to get an ETH loan from someone, covert it to $ and then wait for ETH to fall. When it does you can buy more ETH, pay back the loan and keep the profit.
