I recognize this kind of plays. They dramatically increase value during a 1-5 days. Now the stock has no volume which is a signal of a imminent collapse!
You are 100% correct sir, this is an Pump and dumper from way back at it again. currently price is 4.80 not a bad place to start shorting if you aren't already. Also , there are plenty of shares available to short unlike most small caps. Good luck
