Let’s say a trader has bought Bitcoin for almost $20,000 in December 2017. The current price of this crypto is around $7,000-$8,000. It is evident that he has made a mistake purchasing Bitcoin at its tops. Why do many beginner traders do those mistakes? The main reason for this is lack of knowledge and some typical emotions that make them buying when the price grows.
That bold green candle yells at you “you are the only one not holding me”. At exactly this point you will notice lame people flooding the Crypto forums and the exchanges’ Troll boxes to talk about this pump. But what do we do now? Very simple, Keep moving forward. True, it’s possible that many may have caught the rise ahead of us and it can continue raising, but bare in mind that the whales (as mentioned above) are just waiting for small buyers on the way up to sell them the coins they bought in cheaper prices. Prices are now high and it’s clear that the current coin holders only consist of those little fish. Needless to say, the next step is usually the bright red candle which sells through the whole order book.
If your focus is to conduct crypto-to-crypto trading, Binance is one of the best options. Ranked as one of the most popular cryptocurrency exchanges worldwide, they provide you with impressive offerings along with an extremely low trading fee. Although the Binance platform is a young entrant into the market, it is rapidly growing, and holds a huge selection of altcoins with Bitcoin, Ethereum, and Tether pairings.
The cryptocurrency market, which consists of bitcoin and several other major digital currencies, crumbled June 22 as the majority of the coins dipped by up to 10 percent due to six exchanges in Japan that were ordered by the Financial Services Agency, its financial watchdog, to improve their current practices, and as two exchanges were hacked within an 11-day period.
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!
You could try this instead: Be sure to keep reading crypto news and price analyses — not just staring at charts. Even though you shouldn’t give in to the FOMO and FUD generated by many crypto articles, you still need the news in order to stay apprised of market conditions. Also consider setting stop-loss orders to ensure that your losses will be mitigated in the event of something like contagion. 
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.
