I just realised that most of us don't read posts or follow discussions in this thread. If we all do, no one would still be referring to what seems to me as undermining bitcoin. If you have understand the difference between bitcoin and shitcoins you would know that bitcoin dip is only but a way of market corrections.
People who have been around Bitcoin for a long time can definitely tell the difference between Bitcoin and shitcoin because they are also quite aware that Bitcoin can affect other coins when there is a price correction and also when there is a price increase in the market. But for those who are not able to tell the difference at this time, maybe the person is a beginner who has just learned about Bitcoin and also does not know much about shitcoin so they don't know the difference between Bitcoin and shitcoin.
When you advised against buying bitcoin at deep, I realised that you need more or reading than posting.
Usually those who give such advice are traders who have the goal of chasing short-term profits only so that the person never remembers the long-term advice that can also bring more profits if they really hold it for the long term. Because it would be a shame if someone bought Bitcoin just for trading, even though Bitcoin can be relied on as a long-term investment so it would not be wrong to keep buying it without caring about high or low prices because the goal is not to let it go again in the short term.
