If you want to diversify your investment when you have already invested in Bîtcoin, buying altcoin is not a good step in diversification because if there is a failure in Bitcoin there will also be a failure in altcoin. You can diversify your investment in something different from cryptocurrency such as real estate investment or selling a variety of merchandise, so that if one market fails, success in others will reduce the impact of failure.
What is the need of diversification when we already have our investment on Bitcoin because most successful investors prefer to have only one source which is Bitcoin because there believe in Bitcoin can never be compared to any other investment so they decided to stick to only Bitcoin which is a very wise decision.
And perhaps I see no reason why an investor will prefer altcoin as a diversification for investment because there is no future for an investor who believes on altcoin, however what surprises me at times is that how could an investor see how potential and how real Bitcoin is for investment but decided to choose other alternatives such as altcoin, perhaps the earlier most investors who sees ltcoin as a method of diversification realized they are making a terrible Mistake the better for them because is only Bitcoin and nothing else.
Having another investment aside from Bitcoin is good because you will not rely on your Bitcoin investment before you can make money but it is also good to have a real or physical investment that will give you daily or monthly profit to enable you to hold your Bitcoin to the expected year that you want to sell it. This investment can help strengthen your Bitcoin accumulation power because you will have more money to take care of your financial challenges and still have the money to invest in Bitcoin
