Expanse Booth on the Collision Conf 2018

Omar Alvarez and Marcia Danzeisen was at the Collision Conference 2018. The Collision conference is a conference that takes place in the city of New Orleans, LA. and brings together large companies, presenters, and projects in the tech industry. We had the opportunity that week to meet many enterprises interested in using Expanse. Although it is not an exclusive event of this topic, we have received many requests for integrations and collaborative work.

We have started talks with projects that are interested in partnering with Expanse. Such projects include: geolocation – or applications for notification of indicators for trading, human resources platform – to have a record in the blockchain, a professional profile company – similar to Linkedin, and AIRTM – one of the largest exchange platforms in Latin America.

We will present an alliances upon each agreement and will welcome them to our community. There are very important projects that allow the growth of Expanse. The Expanse team will be participating in other conferences and we invite you to visit our events section.

Having forms of market verification is very important, recently Expanse has more accurate information in Coinlib.io there you can find and compare with other platforms the price and market cap of Expanse, an excellent point of reference to keep you informed.

Expanse CollabMining

The Spanish Community started with the Collaborative Mining, in this activity seeks to encourage other miners to mine Expanse. To participate, the pool is configured and every participant uses the same Wallet. Expanse provides a prize for the first 3 miners that contributes with more power, the rest of the profits are divided among the participants in an equitable manner. In the first test 12 miners were mining for 48 hours and each team member received their share of the mining and prizes.

It is a learning activity for those who are just starting and want to learn how to mine Expanse, it was done in conjunction with MinandoAndo.com and it has been very rewarding.
