I would say at the moment yes.  Most wallets are safer than the exchanges, but when it's a web-only wallet that forces you to create a login, then it's about as safe as any other web service that allows username/password login.

And just an update, Electroneum support has stopped responding to my ticket.  So I'm assuming we're all out of luck unfortunately. Not going to invest into this coin again.

A bunch of us on Github have been posting over the past week about official my.electroneum.com wallets being hacked. Due to no real 2FA auth available, it's probably safe to assume that wallets are lacking in security and if you are using the official wallet, it is most likely safest to transfer it to an exchange that has 2FA available.

Add this to the fact that Electroneum team sent me and email on the same day saying my account was compromised, yet they still allowed the person to send all my ETN out of the wallet. That to me is super shady. If they could detect that my account was compromised, why would they lock it AFTER the funds were sent?

And another odd thing is in the wallet, it says transaction has failed, yet ETN is gone.  Their support is blaming our personal accounts from getting hacked of course.  I've invested in over 20 cryptos and only my ETN wallet got hacked. I'm sure the hackers would have emptied all my wallets if that was the case.

Anyways, just wanted to give everyone a warning to keep an eye out on your official ETN wallets and transfer out if you don't want to risk suffering the same consequences.

What's the advantage of smaller mining pool vs. larger ones?  I'm assuming it's kinda like solo vs. pool mining, just not as drastic.  i.e. the rewards are bigger, but they happen less often.

I have about 185 MH/s of Eth mining on nanopool now, but thinking about making a switch.  Quite honestly I wanted to try zcash or monero instead, but wouldn't mind trying a smaller pool first.
