The profit taking between traders and investors is different, but in principle it must have the price target. Before we buy/sell in the market, we must have a careful plan so that we can stay in the market for a long time.
The market is very dynamic. No one in this world can accurately predict the direction of the market. If you are absolutely sure of the prospects of the portfolio you hold, then I don’t recommend selling everything. If you are not sure, it is best to take all profits and mix in a new portfolio that is still promising. The market will always go through a "bearish-sideways-bullish" cycle, so we need to learn to take profit/stop loss.
Investors are people who have well mapped out the altcoins they invest in. For us traders should be more careful in market conditions, various phases in the market will be faced. It is very necessary to implement a strategy based on research on altcoins and set profit targets for traders, no need to trade with instinct or uncontrollable emotions in making decisions.
