Not all people are able to hold Bitcoin for several years. Moreover, newbies, most of them are panic and falling to sell out their Bitcoin once the price suddenly drops. That's bad.
And some people may not have good funds for a long-term hold.
People who are not able to hold Bitcoins for a long time need to understand that they are trading with more than they should be. If you only trade with what you can afford, then you don't panic at all. Similarly, people who don't have funds for long-term hold need to build capital before trading.
Trading isn't meant for everyone because it requires some skills along with capital, a harsh reality. If you enter the trading world with a small amount of money, you will just end up gifting them to whales who will manipulate the market regularly.
If you want to trade, make up your mind and analyze how you will do it. Just saying "I'll trade from today" doesn't guarantee you success.
Sometimes you can also turn your small capital into big by trading very cautiously and also by avoiding day trading since with low capital day trading is actually impossible since we will lose all the profits to the fees itself then there is no rewards for our risk.
We also can trade with stable coin pair and keep moving the profits to the wallets or into the exchange itself if we want to avoid the withdrawal fee then we can become a trader as well as holder.
