Do you use a password manager? Is there any chance someone got access to your password (i.e. do you use the same password on multiple sites and one of those sites was hacked?), logged in, and changed the password?
Online security is not just the responsibility of the services we log into. If you have a keylogger installed, no amount of security on the target service will help (other than maybe 2FA). If your OS doesn't have the latest security patches or if you don't have up-to-date anti-virus software, then you may want to avoid crypto right now.
I assure you, it's not a scam. Centralized services like MtGox might be, but the code and the protocols themselves are not.
no, I do not use password manager. Let me just say that IT isn't the issue here, I work with software so I somewhat know what I am doing....it's none of those you've mentioned. Coinbase is undergoing a class action lawsuit as we speak for the very same reason....look it up if you don't believe me.
Can you include a link? When I google, I see results relating to Cryptsy.
well, I think coinbase either acquired cryptsy or they were cryptsy operating under coinbase..it's really hard to really know for sure since everything is hidden. But here's a link : http://www.newsbtc.com/2016/12/16/coinbases-faces-class-action-lawsuit-from-cryptsys-victims/
I also speculate that the crytsy owner Paul Vernon is just a scapegoat for bigger scams .
Exchanges are not crypto. They are two different things. If you don't trust exchanges, just by crypto locally or use a decentralized exchange like https://bitshares.org/wallet/#/
