There's multiple charts that helped me predict Bitcoin's bull market and bear market.
The best rule is that you win when you buy "diamond hands", you lose when you sell "paper hands" and buy the dip.
Set it and forget it for 10 years or more.

 

Bitcoin is a digital asset.
Tether and USDC are digital currencies.
ICOs and NFTs are digital tulips.

If you as ask I would say since the market of crypto and bitcoin is too young and it can be effected by the news hugely, there will be a bit harder to predict and the price of bitcoin comparing gold and other assets. I would say as history showed us, if someone is going to invest for long term and needs to predict the price he would be better to forgot the news and tweets by famous people because they will try to take advantage for themselves in first place. So the golden ruse can be to aim for high and forget the tweets.

Well interesting this sentence "buy the rumours, sell the news". But remember this type of strategy use experts now you might be think if this strategy is for experts then now i know about this strategy so am i experts?  Well, its quite yes. But those aren't only experts who can only make profit those are also experts who are ready to face any kind of lose situation. Because they understand its also a strategy for bitcoin. So they take chance about that sentence if it works they are in profit but if it won't work they are in lose. Though they are able so they can easily recover it but beginners can't. So according to me bitcoin is rules less. You just make your own rules be your own rules maker. Thank you

The main key is to keep holding, i prefer not to think about cut loss, it's better that i hold it for long and wait for the time rather than experiencing loss. Other than that, i think another important rule is not to be influenced by the news and do panic selling. Panic selling is one of the reason why bitcoin can be destroyed, we don't want the thing happened in 2017 to happen again right? So people should be a lot wiser now and think thoroughly before they decided to do anything. Investing in bitcoin is pretty simple actually just keep believing and hodl, you might gain lots of profit from there.

So how much the so called youtuber who can predict the market has gained with these "golden rules". According to me you can speculate the prices for any coin based on technical and fundamental analysis but exact prediction is not possible.The rules varies from trader to trader like for some best strategy is to invest "when there is blood on streets" which means invest when charts are red if you have hodl btc.Many have faced looses in search for perfect time to sell or buy because if there was any rule then all will have profits.But one thing is sure invest timely.

No one in the world should dare to say that they have mastered the golden rules of Bitcoin investment. Perhaps the rich and giant whales can affect the price of Bitcoin, but they cannot predict when Bitcoin will rise sharply. Everyone has their own standards. By law, it is impossible to predict completely accurately. It can only be said that you are absolutely optimistic about buying Bitcoin as a long-term investment method.

even if you had watched this earlier yet you will never buy because he is not a legit person tobelieve in and you just give Him sympathy because his  prediction becomes true.

WRONG , you can sell at loss if you have other coins to replace and has potential to make you have recovery.

Because it is your learning and understanding that will make you gain and not other people telling you.

Everyone doesn't want to lose. in crypto I think you have to believe in yourself without following other people's understanding predictions of others, and the most important thing is to buy bitcoin when the price is down, not at the top, that's the main thing that must be applied and one more use your free money not your wife's money

There is no such existing rule when it comes to Bitcoin prediction for those people are only stating their in sights and what they think of how they can be able to make deal with the Bitcoin market. Also, no one could actually predict what will happen or how things will turn out with regards to Bitcoin since it is highly volatile. Golden rules are only created by people for their own personal use or to influence other people to get into the same path like they do. It is up to you if you will follow it or make your own rules to follow.
