What stopped you when the price was low? don't let the sudden increase make you rush into the market- learn to control your emotions.
One of the challenges of some traders is that they don't know when is the right time to enter the market. Some traders feels when the market is red it is always a wrong time to get into the market to trade. If the green should only be considered as the best time to enter the market, I think it won't always be a right decision. Going into the market when it is green is just greedy sentiment for trading.
Sometimes when the market is red it can also be a good time to enter the market if carefully watched. Not all green ends up with profit and not all red ends with loss too.
Traders needs to learn when is the right time to enter the market and not to judge when to enter with a particular signal. Signals are unprecedented and may change faster than it's expected.
Many people enter the market when the entire market is red, because they believe that the market has fallen too much and will definitely go up from here, but that crypto currency falls further from there. That crypto currency may have pumped 100% and then dropped 50%.So it is very important to see at what price that coin was pumped.
There are some people who start entering the market when they see it green. A coin's value can return to its initial position at any time after its increase. Often we don't buy cheap things when they become expensive we try to buy them and trap our capital there.
So I think you should always check your analysis and support and resistance level instead of red and green market.
