The most profitable and less financially risky way to enter the cryptocurrency market is to buy mining equipment mining Bitcoin in part because Bitcoin affects the price of all other cryptocurrencies but also because it's the biggest market. The above statement is only true for people who are able to put their hands on some ASICS and they have a big enough budget to mine in a place where the electricity is the cheapest. This is one of the advantages of Bitcoin. This is something most people haven't seemed to have grasped.

That being said there are some risks involved in mining Bitcoin that don't exist when solely holding Bitcoin.
