Broker will first tell you that you can make lots of money.
they will make you register on the website and claim that they have a special tool that allows them to forecast bitcoins and they can make money off it.
you start off with a small amount and they let your account show 25x what you invested. now the scam begins:
they will first ask you to upgrade your account in order to withdraw the money and there are three different levels 1. 3000 usd, 2. 4000 usd and 3. 5,000 usd.
once you transfer them the money they upgrade your account and you ask to withdraw the profits. then they will tell you that you have to put in 20% of your profit to get the funds transfer and tell you that a lot of customers took the money and left without putting in a commission.
after you pay them the 20% they will then tell you to open a blockchain wallet and they will put the profits in there as bitcoins. you open the wallet and they will ask you to provide them with the wallet key and password and they will input the bitcoins in. when you ask them why cant you send it to my bank account straight they will say for security and they will lose so much money transferring that amount.
after you give them the password and wallet key they will put your profits in as non spendable bitcoins and you basically cant use them. You ask them why and they will say in order for you to be secure and unlock the non spendable bitcoins you have to put in 14% of the amount of bitcoins in your wallet. They will even tell you to change your password so that no one can get into your wallet but once you give them the wallet key they can recreate it do as they please.
when you do put in the 14% they will take the bicoins and disappear.
