Every online web wallet service has an option to export the private key somewhere in many format (don't really remember what is correct) so find out what's the right one. However using online wallet is never a safe choice. I suggest using bitcoin core, electrum or multibit which is less vulnerable than online service
Well... If I try electrum, Will I need to download tons of GBs in transactions?
Everybody is suggesting electrum... Altough it is a great choice (i'm using electrum and multibit HD myself), i don't think they have the option to import private keys... At least not from the GUI, maybe there's a python script that allows you to do this, but i'm not really aware of one.
I think their keys are always generated from the seed, so no "outside" keys can be imported...
There would be 2 options:
- use bitcoin core (and download the full blockchaing). It allows you to import your private keys. It might not be 100% safe, since you exported your keys from a website!
- download electrum, just run it, generate a seed, generate new keys and addresses, and transfer the bitcoins you have in blockchain to the new address. This is the safest option imo, unless your address from blockchain is known as a tipjar, or a public address that receives frequent coins... In that case you're more or less stuck with the first option.
Exactly... I am receiving frequently earnings in my address... I will lose money if a left my address and take a new one.
I am using the install version of electrum and at the same section you described I got the import option. So I think somehow the portable one is unable to do this...
That's probably it... Sorry to spread confusion, i've never had the installed version (only portable).
that's totally fine. Now you know it
you can switch to that and export the priveate then hide it somewhere if you like
Well, the portable version does allow you to export your keys, just not importing new ones... It allows you to sweep private keys tough
I've written down the seed on a piece of paper, that's safe enough for the amount of coins i'm holding
Yeash... I will do something like this. The install electrum wallet seems to be the best option and of course will solve my problem since I can input my private key.
