It's not enough having an investment plan, knowing the right choice to make for every investment defines the investor better. Take for example jumping on every new coin we find on reputable exchange might not be enough guarantee that coin will do well in the future.
Some coin might have good Supply but low liquidity, some might have high market capitalisation but very poor volatility. Although it's hard to predict the accuracy of a coin performance in the near future this why it is always advised to stick to the known which is BTC.
Another option is to spread ones portfolio amongst different coins but ensuring the have a greater percentage in projects with a visible future. It is better to win small and lose less than lose more and win less
this is the reason why you actually only have to invest in bitcoin, even though the majority of altcoins are still cheap, altcoins are centralized assets, while bitcoin is a decentralized asset, wise people will definitely only choose bitcoin as their investment, besides that the liquidity and price volatility will be very high affect the profits from the investment made. The very important thing that always saves investors from losses is that wise investors will not easily suffer from FOMO and FUD, they have good fundamental analysis and Bitcoin is usually the choice of smart investors, not altcoin.
I think when it comes to investment, we will talk about profits, many people will not care about whether it is decentralized or centralized. Bitcoin is decentralized and safer to hold long term but that does not mean it will bring us greater profits. I'm not saying that investing in altcoins is good but I also don't want to deny that, today some altcoins are giving better returns than bitcoin and their risks are also higher. Therefore, depending on the taste of each investor, there is a suitable choice.
The best choice is when your investment offers the highest returns. I invest mainly in bitcoin but I still respect those who make huge profits from altcoins. How can we say they are stupid when they make more profit than us?
Yes those who invest in altcoins to earn high profits are not fools, rather they are a type of strategy people. Here you mentioned that some altcoins are giving better returns than Bitcoin but there is more risk of investors money. Because of this high risk, I prefer bitcoin investing over altcoin investing. Bitcoin investment does not carry a high risk of losing capital. Bitcoin investment offers lower returns than Alcoin investment, but offers greater safety of capital. So Bitcoin investment is best for recruitment. However, if I ever wanted to take the high risk of investing in altcoins, I would take that risk by investing a very small amount of money so that even if my capital vanishes, it will go through a small amount of money.
