Once you’ve gotten your crypto, you’ll need a place to store it. There are all sorts of wallets out there of various sorts, namely desktop, mobile, hardware, and web.
The main thing to keep in mind is that you should never store large sums of money on exchanges or in wallets that hold your private keys for you. Mobile, desktop, and/or web wallets that hold your private keys for you are useful for small sums of money that you need to make everyday transactions.
For significant savings, it is highly recommended that you hold your own private keys.
ETH – For storing and transacting in ether we recommend using MyEtherWallet (MEW supports most tokens from ICO), which is a web-wallet. It is integrated with TREZOR (a hardware wallet), and also lets you transfer between other hardware wallets/cold storages.
Altcoins – First off, often altcoins have an official wallet, so it’s worth googling for your specific coin to see what the best options are for that particular currency.
You can also store altcoins altogether in a multi-wallet such as Freewallet’s multi-wallet or Coinomi, both of which are mobile apps. But keep in mind, the safest way to store your coins is always offline.
Remember! If you store your cryptocurrency on third party services, like wallets or exchanges that hold your private keys, it is possible that your money could be lost if the service is compromised.
