This open source blockchain project plans to offer support for smart contracts and machine learning type service. These AIs will be used in many applications that they hope developers will use to solve tiny, but very time-consuming problems for users.
While many, many platforms offer the ability to use smart contracts, MAN does one better by allowing people to do so with no programming required. I believe soon that these types of ease of use functions will be a requirement for a successful project, and that gives me confidence in a Matrix AI Network investment.
You can, unfortunately, only buy Matrix AI Network on a few small exchanges. The only available trading pair is Ethereum, so you'll need to trade for some if you don't have it already. This can usually be done easily on the exchange or by using something like Shape Shift to swap currencies.
Seeing as this is an ERC20 token you can store it in any wallet that is compatible with Ethereum assets. Many wallets will work perfectly well for this, but if you need a recommendation then you can consider My Ether Wallet or perhaps a Ledger hardware wallet if you would prefer a cold storage option.
