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.
In other words, buy low and sell high via an exchange using limit orders, dollar cost average, set stops if you aren’t in front of a computer, ladder buy and sell orders, use TA, manage risk, preserve capital, watch out for scams, know the tax implications, and consider being conservative in general and not spending your life savings on digital assets.
To be able to take short positions, we need to understand margin trading. Trading on margin means we are trading with borrowed money. On exchanges like Poloniex, we can trade Bitcoin with a handful of coins (there are fewer coins offered for margin trading) with 2.5x leverage. That is, if we own 1 BTC, we can borrow up to 2.5 BTC to trade with. To be clear, this is not 2.5 BTC that we own. Now, on a trade that nets us 10% profit, we are bringing home .25 BTC instead of .1 BTC.
So how do you know if you should invest in an ICO? It’s not about science, it is important to pay attention to the level of seriousness of the project and its team. Look for the project’s website (does it look like a child has built it during computer school?), Who is the team behind the project – Are they hiding behind nicknames or proudly present themselves on their website? Pay attention to the Bitcointalk thread (does it exist at all?) and how the team members respond to technical questions. Is there a large community behind the project? Expect to see a Slack gathering its community. Watch out the amount raised: A project which had raised too little will probably will not be able to develop over time, a project which had raised huge amount – there won’t be enough investors left out there to buy coins on exchanges. And most importantly is risk management. Never put all eggs in one basket and invest too much of your portfolio in one ICO.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
