That is what most people failed to understand, without realizing that when money is only coming from one source once anything happens along the line everything is gone. Sometimes I used to wonder why most people normally have since mentality of having only one source of income, more especially this real estate investment. To be honest nothing good as diversifying your assets, because nobody can really predict what would happen at any given time. Because had it been he put some of his money into Bitcoin investment by now he would have something left.
Of course, diversification is good. We don't know in advance what will happen. But diversification is not for everyone. Especially for new investors. If someone enters diversification without knowing how to invest properly, then I think he will lose all his money. So invest first, gain experience, then enter diversification.
As far as I know diversification is for everybody, unless you are not a human being. As a new investor having another source of income aside from your Bitcoin investment is exactly what would going to help you hold for future. Because you can't just rely on one thing, as long as you are planning to invest in Bitcoin is also very important to have something that would be fetching you money so that Incase if any emergencies arise you would be able handle it without touching your Bitcoin investment.
