I would say that we should set a target of profit percentage like 5 or 10 percent and once the target reached,we should sell our coins and take profits instead of continuously following the price thinking sky as the limit for profit.
I agree with your suggestion especially if you are trading for the short term or trading those sh*tcoins because we don't know if they will be able to recover when bitcoin makes rapid movement again. However, if you are trading or investing for the long term then you should take profit when at least you have 50% profit or double your investment and withdraw your original investment so that you can find again another investment opportunity. The amount left is pure profit so wherever it may go whether it will continue to go up or down, it is still profit but you have to monitor it so that when the buyers are exchausted, you should just sell it all and wait for the next cycle.
That's right but problem is there seem to be a number of crypto traders, especially those without a root in forex trade that think these indicators don't work with cryptocurrencies. No doubt that's blind argument as good knowledge and application of these tools can always aid a trader in reaching well informed trading decisions. I have this preference of using Bollinger Bands in combination with RSI to spot overbought or oversold conditions and then start preparation for possible market reversal.
Some would say that TA doesn't work with crypto because they are used to the movement of the prices in traditional markets but for crypto, its movement is fast so you should adjust your indicators accordingly. Some would say that the movements in crypto in just weeks or months is equivalent to years in traditional market so if you are already familiar with this market then you will know what indicators and strategy can aid you to be a profitable trader.
