Frequently Asked Questions

Disruptive technologies like Blockchain and Cryptographic Currency raise many questions, here are a few we can answer now.

A means of storing value on a globally distributed database, error checked and peer reviewed by millions of computers.
The rate of development in the DeFi (Decentralized Finance) space changes this answer every day. We have personally invested in Bitcoin, Ethereum, Ergo, and Cardano. But we are not financial advisors, and this is not financial advice.
Either by mining (Proof-of-Work) or trading/direct investment (Proof-of-Stake). We can help you build mining solutions, and we can help you decide which Exchange/Wallet is the right fit for your chosen strategy.
Staking lets you pledge a Proof-of-Stake asset to a Pool to earn rewards, which scale with the size of your stake in that asset. For Cardano, once you've traded or purchased from an exchange, you send your ADA to your Wallet (we have links to two higher up on this page), and choose which pool to stake with from the interface within the Wallet. For Ethereum, MEW seems to be a solid choice these days. As an alternative, if you happen to have MetaMask, and you're NOT in the USA, head over to and press "Connect Wallet" to start Staking your ETH.
Binance is the largest in terms of raw volume traded, but there are many others!
