Despite the fact that there are so many coins with higher prices, such as bitcoin being the highest of all. Yes altcoins at this time are more profitable. A friend hinted me on this few months ago and i decided to yield to the advise.
Whenever i open my portfolio, i discovered that most of the altcoins i hold are yielding better profit that most of the main coins in my portfolio.
As a matter of fact, i have decided to continue investing into good altcoins.
you are indeed right but we should keep in our minds that the greater the returns the higher the risk. It reall depends on our risk appetite. For me, i invested on some of the top coins and some of the new coins. For me its better to do this in able to be diversified.
