The Hydro Protocol wants to jump start decentralized exchanges. The largest problem for these platforms is the fact that centralized providers control much of the cryptocurrency market's liquidity. This creates a huge barrier to adoption because traders want to trade where the most action is so as not to miss out.
HOT will allow these smaller exchanges to share their liquidity by pooling it together and then giving any exchanges within their ecosystem access to new market share by matching orders. This would allow these entities to become more powerful in the overall realm of cryptocurrency markets as a whole.
The exchanges which share their liquidity with one another will be incentivized by the platform. These players can earn tokens by participating in the liquidity pools. The tokens, in turn, can be used for membership to the pools, essentially letting them sustain this ecosystem.
It's an interesting project, and it offers the many DEXs the ability to pool their resources in a way that could make them a force to be reckoned with. A Hydro protocol investment is also an investment in the health and safety of the cryptocurrency space's future.
Investors can buy Hydro Protocol from several providers, but they are not the most popular options, unfortunately. You may need to make some alternative accounts in order to purchase your assets. There is however ample trading volume on the available options, and completing a trade should be easy. US Dollar Tether is the highest volume pair surprisingly, but if you'd prefer a traditional cryptocurrency pair, then Bitcoin is a close second.
This is an Ethereum based asset, and that means that you'll need an ERC20 token compatible wallet in order to store your investment. There are plenty of options for this which will work just fine including Meta Mask, My Ether Wallet, or even some hardware wallets such as Ledger or Trezor are capable of storing these tokens. No matter which option you choose, always backup your wallet for safe keeping.
