For Newbie, you might find myetherwallet easy to use for you ETH & ICN - since it also supports natively the ICN token. And you do not have to download the blockchain and keep updating the software to the latest version.
is it really safe using it?
I have tried using it lately and have my ICN store there for sometime now. I'm still worried if its safe to put it there for a long time.
Get a ledger nano s and use myetherwallet with that. Its the safest and simplest you will get per now
Just experiement a little with the ledger nano s first, so you get confortable with it, and make sure your safewords never touch a digital device.
Good suggestion
https://en.bitcoin.it/wiki/Private_keyhttps://github.com/ethereum/wiki/wiki/GlossaryCan read these wikis to get a basic understanding of what it is you are investing in with cryptocurrencies.
A private key in the context of Bitcoin is a secret number that allows bitcoins to be spent. Every Bitcoin wallet contains one or more private keys, which are saved in the wallet file. The private keys are mathematically related to all Bitcoin addresses generated for the wallet.
Because the private key is the "ticket" that allows someone to spend bitcoins, it is important that these are kept secure. Private keys can be kept on computer files, but in some cases are also short enough that they can be printed on paper.
When you send a cryptocurrency transaction, you are signing a transaction with your private key to authorize it, then broadcasting the transaction to the network.
Wallets like MEW or Mist are linked to a wallet file, which contains encrypted private key. The wallet password is entered in order to decrypt the private key so it can sign transactions.
It's not safe to expose private key and password to any internet-connected computer, especially if it's a computer at high risk of malware that you use for all your non-crypto activity.
This is why it's safest to use an air-gapped, offline computer to generate private keys and sign transactions. Then the signed transaction can be transferred to online computer for broadcasting to network.
A ledger or trezor hardware wallet is a miniature offline computer whose only purpose is to generate/hold private keys and sign transactions.
