Tips for Respective Bitcoin HOLDERS :
Types of Bitcoin SCAMS :
1) Never trust anyone who says Invest your bitcoins here/there and we will show how they grow down the line ! Never trust anyone and transfer your bitcoins into any wallet,once they are gone they are gone forever ! So please !
2) Any one threatening saying they know your secrets and request you for Bitcoins,dont even care just hit the delete button !
3) Anybody calls you and says they are from your exchange and request for access/password,just hangup the call !
4) Whatever stories you hear or told,never let your bitcoins leave your WALLET AT ANY COST !
5) Dont buy bitcoins from anyone who says they are selling for cheap ! Buy only from Trusted Exchanges !
Just dont care and move on for any of the above !!
You forgot to mention one more important thing that is proof of key never leave your bitcoin in any exchanges including local exchanges it may hack or scammed in the name of hack anytime as it happened with cryptopia I lost good amount of money in that exchange.
