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!
Cryptocurrency is volatile! There is always the chance that the market will crash, or that you will face some other catastrophe. Cryptocurrency isn’t a centrally controlled and regulated fiat currency. If you lose a coin, or someone cheats you, or your account gets hacked, there is nothing you can do about it (which is one reason why you want to have 2-factor authentication set-up).
Developing a facility with TA takes time, but there are good, free resources available to help beginners get acquainted with the basics. As a place to start, consider checking out the free educational material on BabyPips.com.

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.
