Do I need to worry and create an offline wallet? Can't I keep my electroneum on their site. Won't they provide the exchange? As regal and hextra?
For safety, you should send to an offline wallet.
Keeping it on the website is not as safe as an offline wallet, but if you are not going to transfer it out, at the very least, set up the 2FA and a second email account for backup of the PIN code.
If we want to keep our funds on website, and enable 2fa, will ours coins be safe?
