So it goes without saying that the Bitgrail thing is a warning sign that all of y'all need to keep your god damn money off the exchange. If you don't plan on trading something for the next 3 days, get it the fuck off. Don't think just because it's a large exchange you're safe. Bittrex most recently started withholding people's money because they needed to get verified.
If you hold BTC, Ethereum and ERC20 tokens in whatever you consider be be significant quantities, please invest in a hardware wallet.
Nano S Ledger is the best IMO since it supports the most currencies but Trezor and Keep Key also are popular alternatives and are fine if you're mostly just a BTC/ETH/LTC type of person. I can't stress this enough, you literally have no excuses if you lose money in crypto.
- Don't trade on exchanges that have a history of shenanigans
- Don't leave your money on an exchange unless you plan on trading with the next couple of days
