imported signals ImportedSignals.com They contacted me on Instagram to tell me that I could invest my bitcoin with them for substantial returns within 7 days Alaska

I was on instagram and an account messaged me stating that they could increase my passive income through a bit coin investment into their company.  I was told that with a $100 bit coin investment I would receive close to $3000.  They stated that usually they ask for $500 but they will take any amount of bitcoin to show the investor the process. 

I was then pointed to this website www.importedsignals.com and advised to create an account.  After creating the account I was sent a bitcoin wallet address to deposit the funds in.  I was then told via instagram message from the "supposed account manager " that I would be able to withdraw my bitcoin earning in 7 days. 

In 7 days an amount of money showed up on the site when I logged in , however the "account manager " stated that I needed to pay him a 20% fee to withdraw the earnings/funds.  They will then get pushy with you and force you to send them the 20% so you can withdraw the money. 

In the end they will keep ignoring you when you ask them what bank they bank with and why there has to be a bank withdraw fee.  They will then attempt to block you on Instagram and claim that you are harrasing them.  Upon further research I noticed that there had been numerous scams as such going around.
