Bitcoins and other cryptocurrencies are a tempting target for thieves. Unlike credit card payments or Paypal transactions, a cryptocurrency transaction can't usually be reversed. Here are a few simple tips that can help you keep your coins safe.
1) Do not leave large sums in "hot" or online wallets. Keep your coins in a "cold" wallet -- one which stays offline.
2) Similarly, don't keep large sums in currency exchange wallets. In the past week alone, several exchanges were hacked and traders' coins were stolen.
3) Don't invest your coins in "coin doublers" or high-interest investment schemes that don't provide full financial records. These are ALWAYS scams! Maybe a few early investors will recover their money before the scam collapses, but it's more likely that everyone will be left out of pocket.
4) Treat your passwords, passphrases and PIN codes like the keys to your own home. You wouldn't leave your keys where a stranger could pick them up and use them to enter your house; secure your login information so that nobody can break into your accounts.
Cryptocurrencies are a new technology, and you can't prepare for every eventuality. But by being prudent with your investments and careful with your coin wallets, you can protect yourself against most common threats.
Good luck, and happy trading.
