I was told to send Bitcoin after receiving a check from Zero Gravity Capital

I applied for a remote job and was instead offered work connected to Zero Gravity Capital. I received a $2,100 check supposedly to purchase equipment, and part of it became available in my bank account.

I was then instructed to send $430 in Bitcoin to an alleged equipment specialist. I became concerned and tried to return the remaining check funds, but more payment instructions followed. I am reporting this because the use of a job offer, emailed check, and Bitcoin transfer appears to have been part of the same scheme.
