Paper wallets are a very good and cheap solution, for offline secure Bitcoin storage. You send the Bitcoins to the public address, and when it's time to spend, import the private key to an online wallet. See more how-to 's for wallets:
Ethereum blockchain has more properties than Bitcoin's. When you create an ethereum wallet, you can keep, not only ether, but all tokens that use the ethereum blockchain. See more how-to 's for wallets:
Dash masternodes do special functions in the Dash cryptocurrency network. They do the mixing service, needed to improve anonymity, and they handle all instantX transactions, from creation to confirmation. When an instantX transaction is initiated, the sending address is blocked until the confirmation is done. This helps over the counter transactions, because transaction is completed, immediately. Masternodes block the sender's address from sending new transactions, until the transaction is confirmed by the miners.
Solidity is the language needed to create smart contracts on Ethereum blockchain. To run an application on Ethereum, you need "gas". Gas is payed in ether, Ethereum's token. If you want to test, you can use the Ethereum testnet, where ether are give for free. Gas is given to Ethereum miners, as a reward to keep the blockchain going.
Bitland is an experimental platform using decentralized, trustless models such as Bitcoin’s blockchain to bridge the gap between the government and the undocumented areas. The team is looking to move to a decentralized system in which users download an application which serves as a way to encrypt massive amounts of data and store the data on a public ledger of events. In the new system, the users will have more control over their data, and the public ledger will verify the integrity of records without sacrificing the privacy of users.
Storj, is a cryptoccurency, that gives you coins, for your provided hard disk space to the network. Storj (pronounced: storage) aims to become a cloud storage platform that can’t be censored or monitored, or have downtime.Storj uses blockchain features like a transaction ledger, public/private key encryption, and cryptographic hash functions for security. The decentralized aspect of Storj means there are no central servers to be compromised, and with client-side encryption, your are in control of the keys to your files.

Then you enter fiat currency in the BTM and it is converted and sent to the reqiured address (yours or new). If it's a new address, the BTM prints the Public/Private keypair, so you can import them to a wallet later. The sell process You are prompted with an address, to send the Bitcoins to. Then you scan it with your device and initiate a send transaction from your wallet. When transaction is confirmed, you get the fiat cyrrency in the tray.
Monero is a secure, private, untraceable currency. It has many features, that satisfy the needs for people who care about their privacy, as there are many tools to help you be kept anonymous. Using the power of a distributed peer-to-peer consensus network, every transaction is cryptographically secured. Monero uses a cryptographically sound system that allows you to send and receive funds without your transactions being publicly visible on the blockchain. By taking advantage of ring signatures, a special property of certain types of cryptography, Monero enables untraceable transactions.
