If you are not a good trader and you have confidence on the coin you bought I think you should hold it if you are good at analyzing the market then you can try day trading if you managed to have good successful trades you will be earning good profit in the long run, another risk for holding is that you are not sure if in the future the coin you have bought will pump.
have to believe that for coins like bitcoin and ethereum or maybe BNB you can be sure the longer you will keep it the more it will reach the renewable price from when you last bought it. but for other altcoins it probably won't happen and don't try it for uncertain investments.
To do day trading, I agree with you, you have to really understand the movement and be smart in analyzing it because if you anticipate wrongly then day trading will be detrimental, besides being smart in analyzing and patient in action. if you want to be safe, it's better to invest in coins which will definitely be profitable in the future and will continue to increase.
Bitcoin, Ethereum and BNB have price movements that continue to increase, because it is a popular coins that has a high demand. Popular coins
are very suitable for holding in the long term, because the longer we HODL the higher the price. But if we want to do day trading, we can use
popular coins, but the risk of day trading is much higher. It's not as easy as holding which doesn't need to do anything, holding is just waiting
for the coin price to reach the target we want. While day trading usually has to monitor the market frequently and have good analytical skills.
Day trading must be able to take advantage of volatile crypto prices to take profit, but if the wrong decision is made day trading can make us
lose all the money we have. Knowing this, I prefer holding, which is safer to do and doesn't have to monitor the market every day.
