This post is PERFECT and people need to realize this is a problem. I don't any coins on Bittrex or Poloniex because they un secure. I also recommend storing your coins on cold storage. This way your coins can not be hacked or taken off your computer/Phone.
I recommend using Ledger Blue or Ledger Nano S. Both com be considered storing your coins in a vallet, compared to a wallet.
Would you walk down the street with hundreds in your wallet?! NOT AT ALL...SO please don't do it with cryptos.
I have a post talking about storing cryptos offline....I Just UPVOTED and you got a NEW follower.
