This isn't true for "all" altcoins, not all of them are like that, some of them are actually decent, like for example take the biggest one in example ETH, that is a big one right? So you do not get in and out quickly there and that is why I believe that we shouldn't really be focusing on anything like that, you could buy it and hold it for long term as well.
The method of getting and out quickly is for shitcoins and if you do that then you could probably make some profit with it and that could be the way to go and I agree that we could make money only with that method, but that is not something I would suggest to anyone. This is why the best way to move forward would be just getting greater return in the end for all of this, it couldn't be really that bad at all.
Especially For those who already have a record and history, that's absolutely right sir, but it's very different if I try trading new coins. I myself often get dizzy seeing the movement of coins like meme coins when I enter and trade there, the ups and downs are also very emotional to the point of wasting money.
Indeed, sometimes when the timing of entry is right for the return and the increase in assets is recognized as fast, but indirectly we will enter again and hope to get profit in the next round pump and that's where they fish for a while then waste it quickly.
