I define Storeum is a decentralized market place that is designed for users to buy and sell many products as well as services using cryptocurrencies. It is a platform that supports thousands of merchants and over millions of of listings with no fee requirements.
However, I don't use the services of buying and selling of which Storeum provide instead, I invest in its coin. Its coin is identified as STO, investing on its coin have been profitable for me, moreover I recently purchased its coin because as of now the price is low and I am looking forward to selling it whenever the price gets high enough.
Purchasing its coin is not something complex, however, you can't purchase it directly with fiat money, I got mine by buying some Ethers from Gemini platform and simply exchanging my purchased Ethers for it.
In conclusion, it's not yet a popular platform but I highly recommend its platform because it is tax-exempt, good for self employed entenur and for its support for blockchain commerce.
