GNX is a decentralized, public blockchain project that offers developers a one-stop solution to deploy their projects and to utilize storage options on the blockchain. Their platform allows users to share their hard drive space and to earn tokens for doing so. They have plans to create a global computing system that will support DApps and replace cloud storage and computing solutions like Amazon's AWS.
However, this is a very, very competitive niche, and with the growing number of cryptocurrency projects heavily focused on DApps, storage and cloud computing a Genaro Network investment just doesn't seem very appealing.
While their team is talented and experienced I just can't see them generating enough hype to set themselves apart from the potentially hundreds of other similar offerings available in the crypto space.
It's possible to buy Genaro on several exchanges, but since this is a Singaporean company it may not be the ones you are used to. The highest volume trading pairs are for Bitcoin and Ethereum. Both pairs have fairly even liquidity so it's easy to perform a trade using whichever one you prefer. There is also some volume for the US Dollar tether currency.
GNX is an ERC20 token. This means that it's possible to store them in any wallet that is compatible with Ethereum assets. There are many options that will work here, but some popular options include the Meta Mask add-on for browsers, Coinomi's multi-asset Android app, and the Ledger hardware wallet for cold storage solutions. In any case, you should never keep your coins or tokens on an exchange. Instead, protect your investment by placing it in a wallet that is in your possession.
