Common investors will do the same way. They must be aware that Bitcoin should be the main assets, meanwhile altcoins are just for diversification or additional assets. There is nothing wrong to invest in altcoins, especially investing in top altcoins. We must also expect from the altcoins that possible increase higher than Bitcoin. But we must be careful because there are many failed altcoins.
In the case that ALTs fail, profits from BTC can also help them protect their initial capital very well, even providing a small profit as a gift from the market for their efforts. For example, with 50% of the capital allocated to BTC, if BTC increases by 100%, they will recover their capital, and the capital and profit from ALTs will be their reward.
This sounds simple, but unfortunately, investors sometimes easily change their decisions when they see many ALTs appearing promising, even selling BTC to buy memecoins in hopes of getting rich quickly. What is more frightening is that they allocate most of their assets to this crypto market, and when they incur losses from crypto, they face significant financial difficulties.
