"Profit is profit, small profit is better than none, "
These phrases are largely true when it comes to cryptocurrencies due to the volatile nature of this beast.
Learn the art of taking a profit when trading even small profits. Most of my losing trades are always in profit at some point and I always like I will wait for "a bigger profit."
When you enter a trade, there is something that tells you to execute the trade whether it's market news, some trader signals, or your intuition. (Personally, I love following my intuition and doing my personal research).
Once you enter the trade and you're lucky for it to swing your way, take a reasonable profit as fast as possible. Don't wait for a huge windfall unless the overall market is somehow bullish or bearish and you are in a perfect entry position.
Remember, don't be greedy, take your small win and live to fight another day.
