In my opinion, the best investment in the cryptocurrency space is Bitcoin itself. There are some altcoins that can be a good investment, but I think it is not worth putting a large percentage of money on it.
You got that right, Bitcoin is, and will always remain the best option when it comes to investing in the crypto industry.
Altcoins are for people that are willing to take extra high risks in order to get themselves as much profit as possible in a very short time.
However, I don't take the altcoin industry very serious as the far majority of the coins are nothing more than scams where the operators make money off of innocent people just looking for some profits.
But then again, people go where the money is. And this money sits in the scam coins that get pumped and dumped very frequently. That's what people are looking for.
