Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009.

Cryptocurrencies have seen a surge in popularity in recent years as investors seek alternatives to traditional investments like stocks and bonds. The value of Bitcoin, for example, has increased from $0.003 in 2010 to over $6,000 as of September 2018. While the volatility of cryptocurrencies can be high, the potential for returns is also high.

If you're interested in getting started with cryptocurrency investment but don't know where to start, here are a few tips:

1) Do your research. Before investing in any cryptocurrency, do your research to understand what it is and how it works. Read news articles and reviews, watch videos, and read white papers to get a better understanding of the technology behind each coin and its potential uses.

2) Start small. Don't invest more than you can afford to lose. Cryptocurrencies are still relatively new and highly volatile; there is no guarantee that prices will continue to rise or that you won't lose money on your investment. Start by investing a small amount of money that you can afford to lose if things go south

3) Choose wisely. Not all cryptocurrencies are created equal; some have greater potential than others based on their underlying technology and use cases. When choosing which coins to invest in, do your homework and make sure you're picking ones with real world value."
