No one can tell you what is right for you because it depends on your goals in terms of an investment. Cryptocurrencies are a great opportunity to grow your investment in ways that you won't be able to with more traditional and stable investments like stocks or gold. A smart strategy would be to invest in more than one area and right now cryptocurrencies are still a good place to look to invest.

I would invest a large amount of your investment in to BTC and then consider altcoins such as Ethereum and then others that you have an interest in.

As always, never invest more than you're willing to lose and understand the risks involved.
