If I leave my profits in the trade would I be making more money then if I were to take profits out at every 50% price gain?
The best strategy to take profits is to buy when the price is down by following the Dollar Cost Average strategy and sell little when the uptrend is over.
If we look at larger timeframes, we can sometimes easily spot the reversal of a trend. Selling during these reversals and buying back when the price is low is the real deal.
This is how you should take profits but many fail to spot the reversal and follow the same strategy in the long run.
Also, it has been beneficial to just hold the coins for the long term for many people including me.
There are some coins that I hold for the long term and some coins that I actively trade.
