So let’s take our hypothetical 1 BTC from before and take a short position on Ethereum. We are able to borrow 2.5 BTC worth of ETH and sell it. 30 minutes later, the price of ETH has plummeted 10%. Now we can close our short position, buying back 2.5 BTC worth of ETH; except now, since the price has dropped, we are buying more ETH than what we sold. Our borrowed coin can be payed back and we take the rest as profit!

TIP: A good first foray into cryptocurrency investing is the obvious, buying a major cryptocurrency like Bitcoin. After that, you’ll probably want to trade USD for crypto on an exchange like GDAX. Once you have done that, you could try trading BTC and ETH for other cryptocurrencies. Trading “crypto pairs” can be rewarding, but it is more complex and often more risky than just buying a single cryptocurrency as an investment.

So, how we can avoid those mistakes in our trading? How to be mostly on the green side? First, it is important to note that to trade right requires attention and your one hundred percent focus. Secondly, trading is not for everyone. The following tips are easy to internalize because these tips were “written in blood” (my own blood). However, it’s still difficult to apply them in real-time. After all, we are not rational human beings.
Altcoins and Bitcoins tend to react to each other. Sometimes they do the opposite of each other and sometimes they do exactly the same thing. It is not rare to see Bitcoin go down while alts go up (and vice versa). This is because almost everyone who has alts has Bitcoin, so they tend to move out of Bitcoin when it goes down and move into alts (and vice versa). Almost just as often as this is the case it isn’t the case. Many times, all coins will go up or down together (generally following Bitcoin’s lead). This dance often results in Bitcoin outperforming altcoins, however every x months we will see an alt boom where alts outpace Bitcoin quickly. If you can time that, great. Try to spot it coming and there is big money to be made. Meanwhile, alts can be tricky to just HODL, as they tend to lose value against fiat and BTC in the off season. Learn more about the relationship between Bitcoin and Alts. In a word, alts are generally more volatile than Bitcoin.
Needless to say, Bitcoin’s place as an alternative digital asset among cryptocurrencies has become entrenched, despite likely headwinds it will continue to face as it evolves further. The U.S. Securities and Exchange Commission (SEC) announced in early August 2017 that certain Initial Coin Offerings (ICOs) – which use cryptocurrencies for financing – would be regulated as securities.
An additional common mistake is searching for crashed coins, in accordance to their value against the Bitcoin, hoping they will return to their glory prices. So newsflash – there are coins which are light years away from their peak levels. Take Aurora for example; in March 2014 an all-time high price of 0.14 Bitcoin for one Aurora was recorded. As of the time of writing, Aurora trades at a 99.9% discount – 0.00014 Bitcoins. Could the (damned) Aurora make a move upwards 1000x? You’ll never know. You surely can’t assume a coin being lower than its peak price is an opportunity rather than a falling knife. There are also coins which disappeared and slowly got out of continuous trading – a scenario defiantly worth considering (especially with the low-cap and volume altcoins).
TIP: There are a few sides to cryptocurrency. 1. you can trade and invest in it, 2. you can use it for transactions (anywhere a coin type is accepted), 3. you can break out a graphics processing unit and some software and mine coins (see how to mine coins). Those are all valid and interesting, but with that in mind, this page is focused on “trading” cryptocurrency (and therefore also investing in it). With that said, even if you want to do the other things with cryptocurrencies, you still need to be set up for trading.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
