are you asking for bitcoin or ethereum?
if you asking for ethereum you can use parity.
I'm asking for bitcoin.
+1 for GreenAddress. They started allowing you to use Segwit addresses by default yesterday, which means that your fees may be cut on half, and you will be helping the Segwit adoption by using it on all your transactions.
2FA is also a plus.
Thank you I started to use greenaddress.
Go to greenaddress.it.
Pretty sure that there are no additional charges with that service, you hold one of your keys and greenaddress holds the other so if there was a hacker, he cannot access the funds without hacking both the your private key and greenaddress's private key which is extremely unlikely.
There are others available, such as btc.com. But i would recommend starting out with greenaddress. Been there the longest and has been reliable. Plus you are able to do nlocktime transactions as well.
Thanks timer I started to use greenaddress.it
I will close this thread
