Its name speaks for its intended use, we should only use CEX to exchange, should not and should not be a place for us to trust to deposit our assets on it. In case, you are not a trader but just a pure bitcoin investor, you should stay away from them completely. Only if you are a day or futures trader and you don't have a better option should you use exchanges. But keep in mind that it should only be used for trading purposes and should be withdrawn to your wallet at the end of the day. Never store too much or too long with an exchange wallet.

When we talk about security, we shouldn't care too much about convenience, just because we want to be convenient to use at the expense of our security and privacy. That's not worth the trade-off. We should not trust anyone but ourselves.

I see many people still using Authy and Google authen, that's really a warning to all of us. As I know, Authy was hacked by a hacker eight months ago. Although it hasn't caused any serious problems, it shows that hosting 2FA on online storage services is too risky. And there is no guarantee that they will continue to keep your 2FA data safe in the future. Google Authen is also a good 2FA app and quite popular because everyone trusts Google's reputation. Many people think they are large corporations, so there will be no problem, this is also the next misconception. Even national security data can be hacked, Google data is nothing, don't trust them too much because anything can happen. More importantly, both are closed-source applications, they collect user data without our permission, and we won't know what they will do with our data, so that's a true risk to us.

I used 2FAs in the past because I thought they didn't collect data and it was open source, but then thanks to @o_e_l_e_o I learned that they collect our data. So I switched to using Aegis Authenticator and am satisfied, and it deserves to be a genuine 2FA app.
My advice regarding passwords, 2FA, we shouldn't trust anyone or any organization, keep it to ourselves. Sometimes manual conversion or backup will take time but will bring high security for us. Use open source apps like Aegis, Tofu, and Raivo instead of closed source apps.

If talking about the concept, it must be admitted that P2E is an area that needs to be exploited and developed in the future because it brings profits to both manufacturers and players. But speaking of its future in the crypto industry, I doubt its existence because they are like other trends. Used only to create temporary hype and to be forgotten later. I also don't believe it can be reused in the future or will grow more serious.

I support your decision to invest 100% of it in bitcoin, but to say that bitcoin will replace fiat in the future is highly unlikely and most likely impossible. As long as the government still controls this world, they will never let that happen. It will never be possible that they will let a decentralized currency replace fiat money and take over their power. It can be said that fiat is their leading power distribution system, they control all of us through fiat, and if they lose it, their power will be shaken too.

Well, if you are not confident enough when investing in bitcoin, you shouldn't invest too much in it, it will give you more heartache than pleasure.
Bitcoin makes up more than 50% of my portfolio, but unlike you, I get more excited and will buy more every time bitcoin drops in price. I have never doubted bitcoin and have always been confident in my choices. I bought some bitcoins for $40k last year, but if I could wish, I still want bitcoins to fall more than rise.

What you said is true, I have spent some time researching, and as far as I know, 2FAS is a closed source application, and they just switched to open source in the last 2 months. So it's unsurprising that they collect user data like Google or Authy. I didn't know this for a long time, I just installed Aegis and will moved all the data over the weekend.

I wonder one thing, these open source applications do not collect any user data, which means they will not have the funds to maintain and develop the application in the long run. At some point, if it stops working, will our data still be safe?

If bitcoin hits $1 million, that's its limit, any asset has a price limit, I disagree when you overstate that bitcoin price has no limit. No one knows what will happen in the future, so if someone is already profitable and wants to sell bitcoin when it hits 70k or 100k, there's nothing wrong with that.

Bitcoin price may hit $1 million, but maybe never will, who knows? So in investing, always have goals and plans. Don't be so delusional that you'll regret it later.

Currently, I am using 2FAS, and as far as I know, it is also an open-source application like Aegis, Tofu, or Raivo. The advantage I find superior to other applications is that they are available in 2 versions for both Android and IOS operating systems. The rest of the features are not too different. Do you know about it, and is it safe to use? I'm using it, but I don't know if it's safe for long-term use.

I don't understand what some people are thinking about the market. I mean, every time bitcoin drops 3-5%, they will blame and look for which Fuds caused it, and every time bitcoin goes up 5-10%, they quickly look for which good news drove push the market. They seem to have forgotten that this is a financial market, in addition to being affected by macro information, the market also operates according to supply and demand. Why don't we think more simply increase or decrease is just the difference between supply and demand?

What are the concerns when we mine bitcoin? Don't just blame bitcoin as our earth heats up. In today's modern world, everything needs the energy to work, even your computer or phone consumes power to help you make money. We cannot call them causing environmental concerns or wasting energy. Bitcoin mining too, it consumes energy, but it creates benefits for society, for us, so it can't say much harm. Don't listen to the government propaganda, they just slander bitcoin to keep us away from it.

Blaming is a part of human nature, most will never admit their mistakes and correct them, they will find ways to blame others when they fail. This will mostly appear in the losers.

I agree with many that the government has not been able to fulfill its responsibility to us. But we also need to understand that managing hundreds of millions of people, billions of people is not an easy thing. Therefore, mistakes are inevitable.

Our life should be decided by us, instead of relying on others we should find a way to save ourselves.

To put it bluntly, cryptocurrencies are the get-rich-quick route. You, me, and everyone are willing to take risks to invest in bitcoin just for the sake of getting high returns in a short time. Without the get-rich-quick mindset, we could have invested in gold and real estate instead of volatile and risky assets like bitcoin.
No one wants to risk, losing in investment, but because we want to have a lot of money, we invest in crypto, it is a harsh truth, but I believe many people will not dare to face it.

Do you need clarification? Because if I remember correctly, in 2017, at its lowest point, each bitcoin was worth almost $1k, so buying 2BTC for just $560 doesn't seem right to me.

Moreover, participating in investing with little or a lot of capital has nothing to do with your experience. You have been investing for six years with cryptocurrencies, proving you are an adept investor in the market.

I like to think realistically like you, we haven't broken $30k yet, and bitcoin is showing signs of correction, so thinking about $60k is pretty far-fetched. We all know bitcoin prediction is impossible, no one has the crystal ball to do it. The best way is that we should be prepared for both scenarios of bitcoin, and when it happens, we won't be too surprised.
But honestly, I'd rather this year be the next bear year than bitcoin's bull year.

Even if fiat is phased out, there is no guarantee that cryptocurrencies will replace fiat. This world is controlled by governments, as long as they exist, bitcoin will never be an option because they will never allow something decentralized to break their centralized system. I still believe that in the future, the fiat system will be replaced or upgraded but with a system created and controlled by them, not bitcoin.

If you want to wait until that day, I think it will take a long time and maybe even impossible in our generation. I never thought about cryptocurrency (bitcoin) being used worldwide as a currency, I don't believe governments would accept that. As long as the government doesn't control bitcoin, they will never use it to replace fiat, but controlling bitcoin as we know it is almost impossible.

If it were me, I would also try to allocate time to do both. Having multiple sources of income is the dream of many people, so it's a pity if OP ignores it.
Although it will take us more time and energy to maintain both jobs at the same time, a high income will ensure that our lives will be more comfortable and we will be able to prepare many things for the future and the family.

I agree that by comparison, I also find that people tend to prefer basic paying jobs over commission-based ones. In my country, commission job is very little because it is not chosen by many people, because it does not bring a stable income. But for those of you who are young, unmarried, and like to challenge yourself, I recommend choosing commission-based jobs. Because it will motivate us to work harder, harder to achieve greater things instead of the mentality of contentment when doing a job with a basic salary.

Apart from BTC and ETH, I really don't see any 3rd coins that are definitely profitable for us. Everyone wants to invest in good coins to make a profit, but the problem is that no one knows which is a good coin, research and evaluation are only a part, it cannot guarantee anything. And for a newbie like OP, I don't think it's good to invest 80% of the savings, instead, I recommend him to invest 20%, and the remaining 80% is savings.

Unfortunately, he didn't mention his income or current jobs, so we can't say he failed to get hold of his bitcoins either. Yes, what I am saying is based on the current bitcoin price and the price at which he bought it, if it goes according to plan, then he will make a profit on his investment. I hope he gets back on topic to shed some light on this, personally, I don't think he failed.
