Yes, we must set a selling target when we first buy coins, so that we can avoid greed. Set realistic targets, because in my opinion investing is how to manage our money, not fighting with luck. We do research, buy analysis and set targets, if achieved, sell. And then we do it again as before by managing the profits we have obtained

Agree. Before we buy certain coins, we must know the target (selling price). It should depend on the analysis we do, we decide an entry price. Yes, it should be a realistic goal, never set a too high price. If we try to be greedy by setting a too high price, it may lead to lose. The price increase may not reach the exit target, we can get a lose if this happens. So, it is important to have a realistic exit price (selling price).

Yes, trading is difficult and it takes time to learn it, as I said before my trading knowledge is not good, because I don't have much time to learn trading, maybe if I had more time I could learn trading like your friend

Sure, it should take time to learn about trading. But it is not impossible to master it if we learn seriously. But if you have no enough time to trade, you don't need to learn it. You are better to learn investment, it doesn't require a lot of time. You just need to do it anytime you have spare time (free time).

Currently we see the price of Bitcoin rising again, although we don't know whether this is just a game to manipulate the market. From several analyzes that I have read, it seems that the price of bitcoin will soon rise again and return to touching the previous ATH.

Yes, the price is increasing gradually. It makes sense because we will have halving soon, only 1 day left. The whales who manipulate the market seem to stop it, they have enough coins in their pockets now. It is the time to wait for the exit, selling time.

When we decide to share our data with other people or a platform, it means that it will not guarantee safety. Because, they also cannot guarantee 100% that our data will be truly safe. So, when we have provided the data, it means we are making our privacy more open. It's always a risk and the risk definitely exists.

You're right. There is no guarantee for the safety when we share our data. It is better to keep the secret of our data if it is not really needed to share it. There is no platform that can guarantee our data, even our data can be stolen in the top exchanges in the world. Sure, when we share our secret information, it means to let the possible risks for our personal data in the future. It is not a wise idea, just try to keep it secretly.

It is just for new altcoins got from new projects. If we don't want to join Ponzi, we just stay away from the new altcoins. Old top coins are the best choice if we want to avoid Ponzi, Ethereum is the most ideal altcoin besides Bitcoin. If we just focus on investing in BTC and ETH, there is no way to get Ponzi. Even, there are many people who only focus on Bitcoin investment because they don't believe in altcoins due to too many Ponzi cases.

It's true that this latest bitcoin price collapse makes me very doubtful that bitcoin will ever go to $80k. It's very difficult to increase the price that much. For this year's halving, I didn't really push Bitcoin to high prices. At least Bitcoin has reached a new ATH at $73k a few weeks ago.

I think everyone begins to feel doubtful about the possibility of a new ATH in the halving. Today, the Bitcoin price dropped again to $61k after it recovered around $65k yesterday. I don't understand why the price of Bitcoin easily dropped currently. We know halving is only in few days, but the market is moving opposite. Ideally, the market should begin increasing constantly.

Yes, because of experience and knowledge, they panic when they see prices going down. If they understand the habits and character of Bitcoin, they will be calm and wait because after a correction the market will rise again.

Many people who invest in Bitcoin have no enough knowledge and experience. That makes them easily feel panic when the price drops significantly. They must still feel optimistic if they have good knowledge. It is because they understand it is a normal drop. The bullish season is still very long time, it won't end soon. Specifically that we still have a halving, it is the time for Bitcoin price to increase again significantly.

Why do you think so?
Claiming in advance that two years from now the price will enter a bearish season is just as bad as OP's prediction.
All the patterns till now have been broken, the no trouble ATH, the no ATH before halving, the not going below the penultimate ATH, and so on!

Check again the 4 years cycle. It is divided 2 years bearish and 2 years bullish. 2025 is the last year of bullish season, 2026-2027 is the bearish season. We have bullish season again in 2028-2029. This is what I learned from 4 years cycle of bearish-bullish season.

Again, I don't claim it. It is from the theory of 4 years cycle.
So far, the pattern remains the same. You only can say the patter will change if there is something different in 2025.
