Even 15 years ago, we only thought based on assumptions and research that how a new technology affects people and how people accept it, but those ideas are now being implemented in reality, especially in the crypto ecosystem or in the case of Bitcoin, various large corporate business organisations, investors and ordinary users of the world have entered a game and are following each other, and this decision is gradually making Bitcoin more acceptable to the common people and making Bitcoin a pioneer.This is called game of theory where one person's decision affects another.
Now new investors have learned how small investments can become large at a time.They have also understood that they have to take risks consciously and not by imagining, and not a large part of their income or bonus, but that part is investable, which if lost will not disrupt their lifestyle. Now they have also understood that investment is never a matter of emotion, but it is a matter of planning. Many people may still be regretting why they didn't invest in Bitcoin two-three years or five years ago. My advice to them is that now is the time, buy and keep buying, be patient, one day you will get good profits from it and BTC will become a future asset.
New investors still needs to diversify and stay informed because it’s crucial to managing risk effectively. Most of the no coiners have regretted heavily of not investing long time ago, they should know that regret over missed opportunities is common in life. They should see now as an opportunity to start there investing journey, focus on the present and future because will keep rising and other cryptocurrencies.
I'm don't agree with you if you mean new investors should try their hands on different things, focus is the key to success, a new investor should concentrate on bitcoin investment and not bother themselves with altcoins because most coins out there are nothing but shitcoin and are a sure guarantee to lose money if they are invested into, most times mistakes like this are why some people don't invest in bitcoin, they lose money to a shitcoin and they decide that bitcoin is like that too.
So to any newbie to investment out there, invest in bitcoin and do this investment with your discretionary funds only, this way you can avoid making financial mistakes.
