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.
It does depend entirely on the coin. Some altcoins are great, really strong and undervalued projects that offer huge potential rewards. Others are awful projects or outright scams that turn your investment rapidly to $0. Yes, alts can be great, but it is all in choosing the right one amongst the hundreds of possibilities.
