My dad always tells me to diversify my investments, at first I thought of is as I diversify my coins but no, it is not just my coins, diversify my investments means to diversify it or spread it on different platforms, like stock market, real estate, crypto currency, even on investment on precious metals etc. The reason behind it is to manage your risks and of course to learn and master different fields of expertise.
Diverse investment is certainly safer than investing in one business, this is my mother's formula. Logically, opinions are true, rather than investing in one coin, of course it is better to use a lot of coins whose prices rise analytically. Bitcoin investment is the most important. Because bitcoin is the driver of cryptocurrency, the price is the most expensive and most attractive to investors.
