Notes

• The wallet is a public-private key pair
• Hardware wallet or paper copy is safest - ledger nano s, or https://trezor.io/
• The hardware wallet should have a display. The display is used to generate your key pair if you lose - you can recreate your key pair by 20 words that you write down or remember.
• Exchanges typically store your private key.
• Private key is what is used to access your wallet
• Miners - ant miners pay for themselves in a few month.

Saw your post about skycoin...

I would say *any* crypto currencies that relies on CPU intensive mining is not "appropriate" technology. It's wasteful and dumb :-)

Even the 2nd most popular crypto currency, Ethereum, is very actively looking to move away from wasteful mining and actually already is pushing out a new Proof-of-Stake algorithm:

Basically, look for anything other than PoW (Proof-of-Work).

Here is a short primer on the various other census algorithms:
