I think that if we diversify our investment, we have little risk to take than investing in just one coin. But before you diversify your investments, it should be very important that you carefully study which coins to invest in. Investing in bitcoin is very risky, but we can also be sure that we can have good profit in the future.
I would like only to add here something more. You should be extremely careful and cautious when choosing the stuff to invest in. Besides the crypto and real estate, there are the things that can bring you more profit.
