You guys think off exchange is safer? Not accurate.
Staking is not 100% safe, trojan horse, key loggers or virus can steal our staking wallet and password as well. if you store in cold storage, then it is very safe, but you can't stake there.
Look, mtgox, bitfinex got hacked, if hackers like our computers, can be easily hacked also, they don't steal ours now because we don't have many assets, but small hackers can steal wallets too. Top hacker can steal your money easily if they have our ips. IMO keeping fund on exchange especially bittrex is decent. Their four founders are top security engineers, they have never been hacked for 2 years. I can trust them, even more reliable than my computer, USB, who knows my usd for cold storage is suddenly broken in one day?
You posted, no understanding how computer works. You not take proper precautions to make your computer safe. You better not involve in these if you don't now anything about security. you go to a corner and cry.
