I also chose not to DL the entire blockchain and thus use an online wallet.
If you're worried about security, use dual authentication with your mobile phone instead of email. I assume it's a lot more difficult to hack a phone than an email account.
And yes, sometimes the service is temporarily unavailable. But so are 100% of your banking alternatives lol.
Thanks for the update, MrHempstock, I was considering changing the two-factor authentication method to my cell phone instead, it seems the method involving sending an email has been a bit unstable the last few days.
@bitcoininformation-I was unaware of Electrum, will check that one out as well.
I have been using it quite a while. No blockchain download, instant start up and it runs very smooth. (Armory requires a fair percentage of CPU power, Electrum almost nothing).
