It seems to me that you need to have a lot of different coins in your portfolio. It must be both top coins (top 20 coinmarketcap) and novice coins like the coin of this GoldenFever project.
You need to understand that investing in top coins is relatively reliable but cannot bring such profit as risky investments in new and young projects. Yes, there are high risks, but there is also the possibility of earning much higher.
Well, yes, by investing in a new project, you just dont know how it will behave in the future, perhaps its token will be very high in price on the exchanges
