choosing altcoins to invest of course we have to really know well about the altcoin that we choose because it is very difficult to make a profit.
Bullshit mate. You cannot really know anything about altcoins they are more unpredictable compared to Bitcoin. It will be a total waste of your time, trying to studying more about a coin that will not yield you any profit. If you want to study or know more about Bitcoin, it will be a much better choice for you. At least you have this certainty that you are investing your money and time in something that will yield you profit on the long run.
Many investors still prefer alts instead of Bitcoin because of the possibility to gain huge in a short period (especially if you invest on the current hype like meme coins) that's what they thought. But not realizing that investing solely to Bitcoin is way safer and less risky. It might take time to gain but at least it's much wiser compared to investing in altcoins.
Therefore, buy Bitcoin and keep holding because it's the best choice.
Investors who struggle to make wise decisions often experience frequent losses. I recall a specific instance when Dogecoin reached its alltime high due to influential figures like Elon Musk and some large investors. Many people bought in, expecting higher profits. However, today, Dogecoin's value is less than a dollar. Those who hastily invested are likely regretting it, holding onto coins with little to no value. If they had chosen to invest wisely in Bitcoin at that time, their profits would likely be much higher now. It's important for all of us to make wise decisions when it comes to investing.
