Watch out for scams. There are a few different scams in the crypto world. Anything that isn’t buying a coin with a good reputation is a big risk. Learn more about scams. In short, be super careful about anything that promises free coins, sick returns, or wants you to lend your coins. Buy the top coins using a careful strategy and ignore all the sites promising you they can outperform the market if only you give them X, Y, and Z.
Continually doing these things can lead one to gradually cultivate a strategy: a collection of signals that one is good at recognizing and that have a consistent track record. Some traders only buy or sell once they see confluence: multiple signals indicating the same oncoming reversal or trend continuation at the same time. For instance, they might look for candlestick patterns indicating a reversal on both a short-time-interval chart (like a 15-minute chart) and on a long-time-interval chart (like a 4-hour chart).
Don’t get itchy fingers (AKA be wary of FOMO buying). As noted above, if you have a strategy, stick with it. Sometimes the market will go nuts, and you’ll see epic gains, and you’ll get FOMO (all humans get FOMO, it takes discipline not to react to it). Selling or buying at that time may make sense, but don’t get nervous and switch up your whole strategy without thinking about it. That is often when bad moves are made. If you are going to buy heavily or sell heavily on a whim, consider taking a step back first.
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.
