6. Diversify your portfolio: Diversify your investments to spread out the risks. Spread your money across multiple cryptocurrencies, rather than investing in just one.
adding some crypto assets in the portfolio might be helpful for some investors. but some don't really think this is so important.
there are investors who only focus on Bitcoin, and increase their investment only on Bitcoin. don't care about altcoins with the consideration that if you choose the wrong altcoin assets for investment, it can make investment planning in some assets fail too.
i also think altcoins would be better for short term or trading. therefore I am better off collecting Bitcoins and increasing my investment there rather than adding other crypto assets in the portfolio.
