We have to choose our journey, day trading and holding are quite different though we have the same goal to make money. For some who are full time in trading, they have a good chance to be profitable in day trading because they can spend time to research and gain more experience, for some investors who are busy with their jobs and businesses outside crypto, they don't need to choose day trading, holding along is enough as long as they fully understand crypto and the potential of the coin they are investing.
Without a doubt both are different and require different strategies however it is obvious that if we look at the rate of success of both ways to try to earn money from the markets then we are going to see that investors are on average successful in greater numbers than day traders and this is because it is easier, day trading is by far the most difficult way to produce profits in the markets but since it has the potential to also be the most profitable then it is not a surprise why so many people want to become one.
The fact is "there's money in both"! People who held the right coins are enjoying profits, daily trades who have the third sense for the right timing are enjoying profits!
Why separate trading from holding? Serious traders always have something on a side (holding), and depending on the pair you either stack dollars or sat's (let's use BTC/USDT pair for example), so if you chose the right pair and you stack the right one you will make a profit! Stacking is necessary for this process because many times the price movement will surprise and we need to have a backup plan... and that backup plan requires some funds, one way or another!
