Im new to bitcoins and crytp currency im general.  I was approached byna gentleman named Tom H Kurtzas.  Je works for Blockchain.  He talked me into investing $100 in Bitcoin using COINBASE and then sending it to a blockchain address.  He then informed me he day trades amd I see the profit.  My $100 grew to $265 in a few days (yes this is not alot of money....yet) I told him I wanted to do a withdrawl to test how easynamd accessible the money was.  So I withdrew all but my original investment.  It was easy.  Now begins my investment of $100 ever 2 weeks.  I tried to withdrawl some of the profits and he is suddenly telling me the rules are every 6 months.  I have inbested $600 and my balance is $7K.  Now he is telling me as my acct reaches 10K I have to upgrade or my acct to freeze.  

Has anyone heard of this guy?  He is on LinkedIn.  He has an instagram.  If this is the wrong forum my apologies.

*****Update******
He must be on this forum.  Within 10 minutes of me posting he deleted his LinkedIN and deleted the site that he used to show me my "profits"

Thanks to the help of everyone else.  I rightfully feel stupid.  But I feel better its over.
