Agreed that Blockchain is the easiest to access and use while you're online but definitely a good idea to have a hardware Bitcoin wallet like Trezor as well. Can't ever have too many wallets 

Paper wallet is much safer side to avoid scamming and other issues. In online still Coin base and block chain are good enough and in offline Electrum is best known one. Which is smooth in transaction and fast in less connection as well.

I would agree with you dude but try offline wallet as well it's fare secure than online wallet. Either you can use paper wallet

brain/paper wallet is the best choice amongst all. And i'm using multibit HD & electrum as my desktop wallet, coinbase as my online wallet (which has more transaction) and mycelium as my mobile (android) wallet.

Use online wallets, if you have to do more number of transactions per day. Otherwise stay away from them, as they are vulnerable than other wallets.

Bitcoin core is the original, Multibit and Electrum are decent too.

I want try offline wallet, but for now i don't have time to do it. because i'm not understand what is offline wallet and how it works. i will try it when i have time.

Q Question:

Now I'm using blockchain.info on my laptop to do transactions.
But do I understand well, that this is a "hot" wallet en do I understand well, that this is an "online en also a web-based" wallet?

please a reaction, because may be I'm on the right path now


nice evening, peter
(here in The Netherlands, it is 21.45 uur)

EDIT:

yea, oke I got that, but what was the thing? 2FA code? is that another term for the second password,
or is that another term for that secret sentence of maximal 255 characters?


give me please an EXAMPLE of a private key,please
because this is still very unclear to me,

I just don't understand WAT that private key is and where to find it

Your using bloockchain.info so from their site:

 Two Factor Authentication

    SMS Message - A Message will be sent to your mobile phone containing an authorization code required at login
    Yubikey - Add a yubikey hardware USB device to an account
    Email - An Email will be sent to you containing a code which must be provided at login.
    Google Authenticator - Google Authenticator is a free android and iphone app which generates an authorization code to provide at login.


Those are all options you have to use as a 2nd factor. Goal is even if a "bad" guy gets password hopefully the 2nd challenge will keep it where they cannot get in.

blockchain.info
maybe not the best, but should be Top 5 on the wallet list
