It's true, as you said, without planning in investing, if we don't have some planning, it will make us very greedy, we can't control ourselves in a fluctuating market, it will be very detrimental for us. I like your term the market is a battlefield only people who have special skills can win a battle. I think only stupid people don't want to be blamed, if people have a high sense of curiosity, of course they will learn if they fail.
In fact, this is not a term, but rather a common sense that must exist for everyone who likes to enter the market to trade for profit. Because without learning how to trade or how to invest and how to manage capital well enough, someone will experience something very unfortunate when losses come their way. So obviously there has to be some special expertise if we like to be in the market long term, but for investors I don't think they need to be in the market very long and often because they prefer to keep assets after buying at the price level they want.
I think the usual thing is if we invest and hope to get big profits, there is no word greedy for investors, of course people who buy bitcoin when the price is below $ 1 and then hold it until now are not greedy people, they are always patient and want to sell at a lower price higher, of course the risk always makes us vigilant.
Waiting and being patient is part of the struggle or effort on the part of the investors themselves so that they are not greedy people because they have tried their best when buying Bitcoin at low prices which maybe at that time not many people had the ability to do the same thing. So those who benefit from investment are also very much based on their own beliefs in terms of not having any hesitation to buy when they see that the price of Bitcoin has been at a cheap level.
