Dropbox is expected to emerge on the stock exchange

The Dropbox cloud company has started preparing for the stock market, which estimates 30 percent less than it was four years ago.

Dropobox hopes to sell shares between $ 16 and $ 18 each, so the company would be valued between $ 7 to $ 7.9 billion, far less than $ 10 billion in 2014.

Last year, Dropbox reported $ 1.1 billion in revenue, up 31 percent compared to the previous year.

The company faces the fierce competition of Apple, Amazon, Microsoft and Google. The company says there are 500 million registered users from 180 countries, with 11 million paying for the company's cloud services.
