They dont close your account based on that. They may file a SAR on you but not close your account. During the coin days many folks deposit this much and more in a week's time. There are folks being SARed and actually interviewed by FBI but no account closure from that. (Those who were interviewed also came out fine.)
There are just too many missing parts in OP's story that dont add up.
