point of main, holding need long time but trading is short time which you can make money everyday from trading.
First of all you need to understand holding or trading everything you need to have knowledge. As an experienced trader earns a lot of money by trading daily. On the other hand if a good investor can buy good currency then he can also get profit.
Trading is good and profitable to those who are well experienced and have good understanding with the market. Truly, tons of money can easily be made from trading, as an experienced traders, and yet losses are inevitable even as an experienced traders.
Trading takes a lot of time for one to gain experience. Reading and understanding candles sticks, the candle movement. One should be able to stay updated with news and current happening around the world that has effect on the crypto industry. Trading takes lots of dedication and discipline. Poor emotion stability in the market when trading can either ruin your trading account or make you jump with profits; it can make you jump in/out of the market too early or late.
I trade, but hold for long terms, and I hold coins that are on the top list, with Bitcoin as the first. Bitcoin is possible to give remarkable returns when the market faces a bull run. With current market surge, all Bitcoin holders are smiling, even as the crypto community is intrigued with the news an up coming development.
It is safe to invest for long term, and to invest in profitable crypto assets like Bitcoin, and some top good altcoins like ETH, BNB, Solana etc.
