There are many ways to take advantage of the current crypto boom. The two most popular coins today are Bitcoin and Ethereum. Bitcoin and Ethereum prices have been experiencing high volatility because of global instability, including trade wars. Ethereum differs from Bitcoin in that it has transaction tracking built in, which makes it less anonymous, enabling fraud prevention. Developing your own cryptocurrency from scratch requires significant software development skills, including the ability to create your own blockchain as well as its associated logic. You have to research several issues before development even begins including deciding what issue your blockchain will solve.
Assuming developing your own cryptocurrency from scratch is too cost and time prohibitive, the best alternative is building off of an existing cryptocurrency.

Making your own Ethereum ERC-20 token takes about an hour. Here are some tutorials that will show you how to make your own token:
