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.
The other major risk to be aware of is that hackers are always looking for vulnerabilities to exploit. One example is the more than $30 million worth of Tether coins that were stolen. The most surefire way to ensure the safety of your coins is by using a hardware wallet such as these by Ledger. Keep in mind that this will slow down your ability to trade those coins, as you will be transferring them between the device and your exchange accounts (more on wallets and exchanges soon).

To perform cryptocurrency arbitrage, you need to find an opportunity where you can buy a cryptocurrency for less than you can sell it on another exchange (minus the fees and commission). Once you’ve found one, all you need to do is simultaneously buy Bitcoin on the lower-priced exchange and sell on the higher-priced one. It’s easy to make hundreds or even thousands of dollars in just a few seconds if you have enough funds.


Watch the Order Book. The order book (found on all exchanges) can give you a good sense of what buy/sell orders are “on the books” (sitting on the market waiting to be bought or sold). If you see a lot of sell orders at a certain price and want to sell, you may aim to sell under that price. Likewise, if you are waiting for the price to drop to buy, look at the distribution of other people’s buy orders. Just watch out for artificial buy walls and sell walls (large orders that aren’t meant to fill). You’ll almost always find buy walls and sell walls at support and resistance levels.
Don’t get itchy fingers (AKA be wary of FOMO buying). As noted above, if you have a strategy, stick with it. Sometimes the market will go nuts, and you’ll see epic gains, and you’ll get FOMO (all humans get FOMO, it takes discipline not to react to it). Selling or buying at that time may make sense, but don’t get nervous and switch up your whole strategy without thinking about it. That is often when bad moves are made. If you are going to buy heavily or sell heavily on a whim, consider taking a step back first.
Arbitrage is the process of buying then immediately selling something for a profit. This is possible when there are price differences between different marketplaces. For example, buying certain DVDs at your local store for $10 only to sell them online for $20 each, doubling your money in the process. In our case, it’s buying cryptocurrency on one exchange and then immediately selling it at another. Arbitrage is based on exploiting market inefficiencies and is popular in all kinds of markets, including the stock and FOREX markets.

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 any significant investment in the space, I’m using the pick-and-shovel strategy to gain crypto exposure in the portfolio. Which “play” am I investing in? After much research and networking and grovelling, I’ve finally found a very good target which is ironically, a mining operation. I’ve been looking for an exchange play but haven’t found one yet…(so if any of you know of a solid one looking for funding, feel free to lob it my way :-))
Another thing I need to make clear is the type of trading I do - day trading. My base currency is Bitcoin, which I use to buy Altcoins like Ethereum, ZCash, Golem, etc. When I make a trade to buy an Altcoin with BTC, I could end up selling the Altcoin back for BTC within a matter of minutes or hours. All of my profits are converted back into BTC at the end of each trading day.
Categorize your investments and look at the long picture. In the process of your research, you’ll eventually realize you’re coming across a few different categories of coins. For some of them, you believe they have good teams, great vision, amazing publicity and a track record for successful execution. Great! Put these into medium or long-term holds and let them marinate into a delicious tenderloin. When the price dips, don’t even consider panic selling because anything in your medium or long-term portfolio should remain untouched for a set amount of time. BNB is a good example of a coin Miles considers a long hold. Recently, it dipped 20% for a while, and within our community, we witnessed some sell-offs to preserve investments. A week later, it jumped up almost 3x for a period of time.
