How to buy and Sell.
Well, if you want to put money down on cryptocurrencies:
In the U.S.A. the most direct route is to get an account at Coinbase.com. You will need to link your bank account, have identification for KYC (Know your customer) And a table to pound your head against.
Nothing is simple in the cryptocurrency world. In an effort to keep your Bitcoin / Alt currencies safe, everything seems to be overly complex and frustrating.
You can also purchase Bitcoin at a Bitcoin ATM and put it away until such time that it is an everyday occurrence.
Coinbase is associated with GDax, a cryptocurrency exchange that also lists Ethereum and Lightcoin.
Other exchanges include, Poloniex, Bittrex, Bitfinex,
Open ledger.
At this point you will be scratching the surface of truly a Brave New World. (Thank you,

Some helpful hints:
Get a camera with a memory chip just for cryptocurrenices.
Take picture of screens and write the passwords down.
There are to many numbers and "seed words" for you to ever remember them or find them again on a computer file when you lose your wallet information.
Do not store anything like passwords or seedwords online in the cloud.
Cold storage is best; in a paper wallet or a harware wallet.
