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.

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!
Here again, it is important considering a number of factors when choosing a stop loss level correctly. Most traders fail when they fall in love with a trade or the coin itself. They may say, “Here it will turn around, and I will get out of this trade with a minimum loss, I’m sure”. They’re letting their ego take control of them and unlike the traditional stock exchange where extreme daily movements are considered 2-3% in value, Crypto trades are a lot more riskier: in my life as a trader I’ve seen a coin dumping by 80% just in a few hours! And nobody wants to be the one who is left holding it.

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.
