So far, everything we’ve discussed has involved taking a long position on a coin. That is, our focus has been buying a coin at a lower price than what we think we will be able to sell it at later. What if we have some indication that leads us to believe that the value of a coin is about to decrease? In this case, we could take a short position, which is the same technique that made some people boatloads of money during the 2008-2009 housing bubble.
Is a digital asset which is designed to act as a medium of exchange that uses encryption to secure transactions and control the creation of new currency units. Cryptocoins are a subset of digital coins. Bitcoin was created in 2009, thus becoming the first decentralised Cryptocoin. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.
The crypto world is a uniquely perfect environment for arbitrage. As William Belk argues here, the combination of it’s distributed nature, regulation, security, availability, and anonymity factors means that the marketplace has many inefficiencies, and that “arbitrage opportunities will continue indefinitely.” For example, some markets pay a premium for security, geographical location, or simply because they don’t know they can get it cheaper somewhere else. In some cases, the price discrepancies across different exchanges can be as much as 43%.

For instance, you might have a day trading strategy that exploits differentials in tightly correlated cryptocurrencies: BTC and ETH, for example. If you think that BTC and ETH are tightly correlated and you see that ETH is disproportionately low, you might buy ETH with the expectation that ETH will rise up again to restore its typical relationship with BTC. However, this might be a case of contagion: the whole market is going down. In this case, your technical analysis could be your downfall: you’ve just bought into a position that’s still going down.
You could try this instead: Buy and sell on multiple exchanges; then, when you see those moments of indecision in the market, buy more of the cryptocurrency on the exchange with the lowest price, while simultaneously selling some on the exchange with the highest price. That way, your risk is mitigated: if the price rises, you’ve made money, and if it drops, you can buy back in at the lower price.
Fundamental analysis is a methodology that was first conceived by the late American Investor, Benjamin Graham. It was then later popularized by Warren Buffet, currently one of the world’s more famous value investors. Fundamental analysis is a concept that is most often applied to companies, but it can just as easily apply to digital assets such as Bitcoin. Instead of metrics such as the P/E ratio, factors such as the following can be used as part of any cryptocurrency related fundamentals analysis:

Don’t be greedy. No one ever lost money taking a profit. As a coin begins to grow, the greed inside us grows along with it. If a coin increases by 30%, why not consider taking profit? Even if goals are set to 40% or 50%, you should at least pull out some of the profit on the way up in case a coin doesn’t reach the goal. If you wait too long or try to get out at a higher point, you risk losing profit you already earned or even turning that profit into a loss. Get into the habit of taking profits and scouting for re-entry if you want to continue reaping potential profits.
