I think that  Cryptocurrencies are a good investment. It is always good for investment. Investment is one of the ways to become rich. Many people think that they can afford they houses or education with their 8 hours/day job. This is very difficult. Mostly, people work all their life for nothing. I believe investing in  Cryptocurrencies is a great idea. In 20 years, we will have new millionaires thanks to  Cryptocurrencies. Beside  Cryptocurrencies, I propose to invest in real estate, or in startups. Just find a good one and invest in it. Startups dealing with electronic and computer science are good. Just look around you and you will find a good one. Good luck!
