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.
When you are choosing the crypto exchange, look at and compare cryptocurrency platform fees, among other things. Using some crypto exchanges you will pay a percentage of each deal, using other ones you will pay for income and outcome transactions. You need to pick what fits you more. For example, Bitfinex charges Maker 0.1% and Taker 0.2% in fees based on the volume. Kraken charges Maker 0.16% and Taker 0.26%. European BitBay charges both types at 0.43%.

Don’t FOMO. This is a spot that people most frequently lose money on. A dash of manipulation, two tablespoons of media hype, a cup of CME and CBOE announcements, and a generous handful of FOMO drove Bitcoin prices from $10,000 to $20,000 in December. Since that time, Bitcoin fell to a low of $9,000 and is currently sitting at around $11,000. It’s easy to look back and say, “if only I waited one month, then I could’ve bought at $9,000 instead of waiting for Bitcoin to hit $20,000 again for me to break even.” But the reality is, the combination of 1) being greedy, 2) investing blindly, and 3) FOMO were likely large contributors to the purchase at an all-time-high. Even in the crazy world of cryptocurrency, if a coin pumps that quickly, it will correct — it’s a matter of time. Speculative pumps are almost always followed by dips. While trying to jump onto a train going full speed sounds like something straight out of a James Bond movie, I’m sure most of us can agree we would probably save some limbs if we just waited for it at the next stop.

UPDATE: I do not recommend paying to enter a Cryptocurrency mastermind group – I’ve tried a few and found the ROI to be disappointing. I am now focussing on growing my portfolio passively utilising a cryptocurrency trading bot, the renowned Notorious Bot. Having a bot that trades for me, without emotion, using an advanced algorithm, allows me to grow my portfolio in the background without it cutting into my time or stressing me out. You can familiarise yourself with the basics of cryptocurrency trading bots here. 
Bitcoin tends to find resistance at whole number points. For example, at $4.8k and $4.85k. It also absolutely loves to react at whole numbers like $10k and either drop or run. If you know you want to take profits soon or buy soon, keep an eye on those whole numbers. If you feel like the run must almost be over, pull your profits before the whole number is reached!

A lot of people in the markets love tips. Ignore them, they will lead you astray. All information is incomplete, all trends can reverse at any time, don’t listen to tips, don’t take advice, don’t believe you are right, or that someone else knows anything. Instead, soak up every shred of information you can and filter it down and try to make sense of it. If it doesn’t make sense then leave that investment alone. Stock markets, commodity markets, crypto markets, they will all strip you bare if you let yourself be lead. If you are not ready to go it alone, then don’t go at all.

Trading strategies are there to provide objectives for traders to earn more with lesser capital; just like how a successful business should operate. There are a lot of trading strategies that are being written all over the internet today, but what we’ve noticed is that most of these so-called “strategies” are just plain common sense; something that is hard to come by nowadays.

Hold some coins, range trade some coins, keep money on hand for a dip, and set some high-ball and low-ball orders. If you want to ensure you are happy no matter which direction the winds blow, then be set-up to benefit from whatever comes next. If you have some coins you hold, some coins you trade daily or weekly, some money set aside for a dip, and some high-ball and low-ball orders set, then you stand to benefit regardless of what happens. It can be tempting to cash out of crypto or go all in, but both of those can be disappointing if the market goes in the opposite direction you were hoping for. It isn’t always the most profitable move to run a strategy like this, but it can help you to gain experience and have something to be excited about in almost any market. TIP: Note that diversifying your strategy and holdings eats into profits, but offers flexibility. It is a trade-off.
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.
