What I mean is that, the investors should not concentrate on a particular investment, else the may experience a bankrupt in the future if their business is not functioning properly.
This talks about diversification in business and investments, we can't just afford to have all our eggs on the same basket, because we can't predict the future, hence there's a need for us to diversify our investment on other profitable assets, also, we have to understand how to differentiate assets from liabilities, having bitcoin as our first priority is a good decision, then we may consider some other top altcoins as additions to that, while alternatively, we may also diversify by investing on physical assets like real estate, gold or landed properties, which all could serve as a source of income to us and when one is it yielding as we may expect, we can be rest assured other sources could provide us the necessary income needed as our plan B.
