As i can see, not many people are read the whole topic. I suggest everyone to read all replies before posting your reply.

If you don't agree, then make your words more argumented. I'm tired of people that just saying "nonsense" to anyone they don't agree. Look how my posting is structured and argumented. If you think that my arguments are "nonsense", then prove it, aswell as I'm trying to prove my beliefs.

I've already told that i have not any personal hate against Bitcoin. I am repeat: read the whole topic.
I've already told about issues that Bitcoin have, and Ethereum have not, but let me clarify.
Bitcoin became more centralized due to ASIC mining. China is the leader in the Bitcoin mining industry, the most of Bitcoin's hashing power are centered in China, cause they can produce ASICs cheaply, and electricity is relatively cheap there. By statistics in the Internet, China may have hashing power over 51% of the whole Bitcoin network. That means China can perform 51% attack on Bitcoin network, but currently they don't do that. But how can we trust Chinese government that they will not suddenly consider Bitcoin as the threat of Chinese currency? This is not conspiracy, if China have power to attack Bitcoin, this will be disaster for it. Cryptocurrency needs to be decentralized, for long-term investment.
I think this issue is the most dangerous.

I've already told: do what you want, this is your money. My purpose is to share my thoughts with crypto community.

Of course Bitcoin can give money as any other crypto. But by "what Bitcoin exactly can give?" I mean it's intrinsic value. If Bitcoin have clear disadvantages, like centralization, that will break it in next several years, i suggest to not hold it for too long. The last decision is on you of course.

I haven't told that LTC, BCH or XMR are better than BTC, I've mentioned them because, many developers are see deep problems of Bitcoin, and are trying to solve them.
The main disadvantage of Bitcoin, is that it cannot be changed. Any major changes of source code leads to new cryptocurrency. Ethereum just more flexible, and have gone the difficult way to prove it's value.

I really like your enthusiasm, really. But read the whole topic. Decentralized banks are not possible with Bitcoin, cause it's centralized. If there is cryptocurrency that faster than Bitcoin, more secure, durable and convenient, that crypto may become more important in the near future. And this is not necessary to be Ethereum, I just don't see better, long-term alternative, in case if Bitcoin will totally fall.
Don't be overwhelmed by Bitcoin dominance, in crypto market, changes can happen in the matter of days, you're all know this better than ever.

I'm not saying that Ethereum is more profitable than Bitcoin, I'm trying to say that Bitcoin have problems that will lead it to fall, and Ethereum have enough technical concrete to withstand, and maybe become next dominant.

And one more thing, I'm not saying that Bitcoin will crack right now, I'm saying that it happen in next several years.
I'm not forcing anyone to beleave me or do like i suggest, we need to talk about anything regarding Bitcoin, to make cryptocurrencies better instrument for investing, trading, and use.

I think that there's misunderstanding of my position about Bitcoin, Ethereum and alts.
I have no negative impression about Bitcoin. This forum exists for discussion, not the praise of Bitcoin, aswell as other crypto. I just looked at the code of Bitcoin and whitepaper a bit, looked at the history, looked at the other cryptocurrencies. I don't blame anyone that love Bitcoin, cause i love it myself. But i wanted to express more critic view, that catched my mind.
Because of that, i told:
I'm not ordering anyone to buy Ethereum, I'm just expressing critic and not so ordinary point of view. The last decision of what to do is on you of course, and i know about investment/trading risks, obviously, we're not kids here.

I'm not fully against the TA, if you spotted some pretty predictable property of price using the set of indicators, developed and tested trading strategy and have good money management, then of course go ahead and trade.
Just my personal opinion: long-term: Ethereum, short-term and active trading: other alts.

Strange statement, Ethereum not shares all problems with Bitcoin. Just think a bit, why are there so many cryptocurrencies developed at different times? You really think that they were developed, just so developers can profit from it? You right! But not all crypto were developed for that purpose. Litecoin, Bitcoin cash, Ethereum, Monero, and many others were developed to mitigate drawbacks of Bitcoin, but have their own issues aswell. I think it's not impossible for some cryptocurrency to be decentralized, fast, cheap, and convenient, if developers are trying to improve base ideas of Bitcoin.

I'm not Ethereum "fan", I'm not even the "fan" of crypto. I'm researching and learning cryptocurrencies aswell as you all do. I just take it seriously, not as someone that too "excited" or making "fun" of it. This is not bad to be excited or making fun of it, this is just my personal, cold-blooded "inspiration".
Other cryptocurrencies are not so depended to Bitcoin as you may see. Price doesn't tell that much. If Bitcoin get cracked, hacked, breaked or whatever can happen, the price of other crypto will drop, definitely, but that doesn't mean that Ethereum or other cryptos just disappear.
I can't get why all of you telling me that some other crypto is using Bitcoin "ideas", that Vitalik inspired by Satoshi, we're all already know that. This sounds like this is something bad to be "inspired" by someone, and use something as reference in project. If to think that way then, Satoshi is a bad guy too, because he used ideas of Nick Szabo, and Bitcoin is a bad project because it used ideas of Bit Gold as reference. You really think it's so bad? I just can't get, why are pointing me that?

I don't want to hurt someone, we are just discussing.

For HODL, you don't think about volatility. It's long-term investment, your trust in the future of the asset.
Seashells were the firstborn, adopted, and accepted currency in history, aswell as, rice, silver, and gold. But this is not reject the fact that they have weaknesses, that in long-term, made them not valuable or practical. Paper money replaced gold cause of convinience. Cryptocurrencies is intended to replace fiat, but Bitcoin have long-term issues, that i described earlier.
There is nothing wrong to modificate ideas of Bitcoin to make better crypto.
That everyone are just hyping now, doesn't mean it will remain dominant. Bitcoin is accumulating deep problems, that will break it in next 5 years or a bit more.
What? Bitcoin can crash by itself due to issues i mentioned above. And price of Bitcoin doesn't reflect that. Price of any asset represents psychology of all participants in the market. Price is "strong" because everyone see it like this, and cause of that you can't predict the price. Can you predict people behaviour? And price cannot predict anything, just cause it looks "strong". But psychology can change, and you better be ready that dominance of Bitcoin will last not too long.

Why big companies not bought Ethereum you ask... Hmm... Because they already bought it. Ethereum encreased in price aswell as Bitcoin, they just diversify their money, but put more in Bitcoin because it's the mainstream.
Bitcoin can't handle many transactions, the volume doesn't matter, send you 1$ or 1$ million. The number of users of Bitcoin network is encreasing, the quantity of transactions are also encreasing, that is the matter.
Big players on Bitcoin market initiate any big move. You really thinking that Bitcoin suddenly encreased in price because it's so valuable out of nothing? And then, when something happens with Bitcoin price, that is reflecting on price of other top cryptocurrencies. Bitcoin is the face of crypto market now, and cause of that other crypto tends to Bitcoin, like childs tends to their parents. But when they grew up, they are starting to live independenly, and in many aspects be better than their parents. Society is progressing like that, everything is progressing like that, new replace old. This is called evolution.
If you want to succeed, you need to be one step ahead of everyone, otherwise everyone will go far away, and left you out.

I think a big mistake that people do, when looking on Bitcoin, is only profit. There is nothing bad about it, we all need money. But Satoshi Nakamoto doesn't made money machine so everyone can get rich, Bitcoin is money itself. I just want people to understand why he bringed this technology. Bitcoin is very successive experiment, it showed us that we can put our trust to cryptography, decentralized public ledger that we call blockchain. Amazing innovation that early adopters bringed to the masses. But cryptocurrencies need to evolve further, while we looking only on price, developers and programmers from around the world giving new technologies based on Satoshi's ideas. Do your own research, look at the Bitcoin deeper, at Ethereum, at any other cryptocurrency, if you want to be on the wave of crypto technologies, you need to be more inovative, always reconsider your opinion, as Satoshi do, back in the 2008.

I'm not talking that Bitcoin is a bubble, i also dislike when people talking that crypto is a bubble, i'm trying to say that Bitcoin is not perfect. Satoshi can't see the future, he pushed us further to the future of cryptocurrencies. Bitcoin is just not ideal, Ethereum is natural continue of crypto world, Ethereum not ideal too, but it have more promising future. I love altcoins when we talk about speculation, there are interesting projects aswell.

How kind of you.
As i can see you don't know what decentralization it is. Bitcoin network became more centralized than before cause of ASIC miners. And you know where ASICs can be produced cheaply? This is China my friend. Ethereum is ASIC-resistant for decentralization. So, Bitcoin is more decentralized than Ethereum, is total nonsense.
Here you are:
1. Ethereum is faster:
Transaction verifications are prossesed in 10 seconds, as opposed to 10 minutes in Bitcoin.
2. Switch to proof of stake over proof of work carries many technical advantages.
3. Smart contracts are more productive than transactions in Bitcoin.
4. Ethereum's dApps open a new possibility of edge computing.
5. Ethereum is more decentralized.

Bonus:
Ethereum network allows developers to build complex applications, many inovative projects are running on Ethereum network. You always can google it.

I want to share some thoughts about the reasons why HODLing Bitcoin is risky, and why you don't need to build any TA strategies for trading Bitcoin.

First: why not to HODL Bitcoin?
HODLing require from you to hold long position for years. You assume that the price will go up long-term. But why it should go up? General reason for that assumption is that many and many people, enthusiasts, developers, investors, organizations of the whole world get to recognize Bitcoin more. This results to encreasing money flow and price. But in essence, what Bitcoin exactly can give? Of course, decentralizaton, self emission, a bit privacy. But Bitcoin lack some features, that other cryptocurrencies have. Bitcoin can't give people enough transaction speed and convinience. Bitcoin can't give developers convinient methods to build applications. Bitcoin can't help organizations and investors get rid of the fear that this is all just a bubble.
Bitcoin is important step to revolution of the whole financial system, but not the last. It exists now, because not many people understand that Bitcoin is relic of the past. Ethereum is much more promising than Bitcoin with it's smart-contracts. HODL Ethereum not Bitcoin, when the disaster comes, Bitcoin won't survive.

Second: why not to trade Bitcoin?
How are you predict price of Bitcoin? TA indicators?
Ranges? Support/Resistance? Price action? Candle patterns?
We all know about bad statistic of these tools. Almost anyone can't say why they using RSI, MACD, MA, CCI, Bollinger bands and other indicators. Why tringle pattern should end in desired direction? How these tools can help you predict, statistically unpredictible price? Price doesn't owe you something.
Price drives by big speculators, sharks, whales, market makers and other monsters of crypto ocean. They are trying to eat each other. Doesn't you noticed that Bitcoin pumps when new antminer ASICs are sold? You think that Elon Musk that smart to buy Bitcoin? He's smarter! Hype of Bitcoin is rising, why not to sell Tesla cars for Bitcoin?
But just a quick and realistic glance at the Bitcoin price chart of last several months gives clear vision of situation:PUMP!. And what happens after pump? Have someone an answer? Sit down, take A+, of course a DUMP!
You need to have insider info. With that, you'll get more chances. Or be the shark, while this almost impossible.
You can keep trading TA of course, scalping works in every market. But how many succeded traders do you know? Those youtubers? They get money from traffic, adverticement and affiliate programs, not from your success.
If you don't beleave in the future of cryptocurrencies, just want to earn some paper money, then HODL Ethereum or speculate with top altcoins with high liquidity and volatility.

Tell me your opinion.

Edit;
For better understanding of topic, you need to read all replies, cause there are some clarifications regarding this topic.

If strategy is built on the set of rules to get rid of emotion, and analysis is quantitative to make your trading system more accurate, then DEMO is the best choice to pre-test it. Then go small to LIVE for test, and in the end put more money when you done testing for some time.

If you call the "trader" every people that "invested" 50-500 dollars. Then yes, i think it's true. But put some thought into the term "trader" and then you realize that someone is the trader when he trading for some time, and don't lose his money. The other "traders" needs to be called strangers, gamblers, begginers or losers. So, in essence i don't agree that 95% of true traders are losing. If you have your strategy that keeps working for you, it will make you the trader.

Many people thinking that HODLing is safe, much safer than trading, this is not so obvious IMHO. How to determine best time to start HODLing? Now, if you look back to the past prices of Bitcoin, you may think it's too late. But when you wait for several months, you regret that doesn't bought Bitcoin, when you thought it's too late. If you has confidence to buy it, price may go up, until fear will step above of euphoria, and then you sell it, not holding for long. This type of HODLing reminds the bad trading strategy. If you beleave in Bitcoin, you need to hold it, not to sell it for the piece of paper, but to await for the times, where goods will be measured with Bitcoin. This is true HODLing, any other time before that future, is risky speculation. If you can't wait for too long, then go for trading, where risk and intelligence are struggle to determine the future of your wallet.
