To bring to 50 cents it would only be about $45,000 market buy. It is nowhere near 6 million dollars to bring it to 1 dollar.
I don't think you understand how the market cap works. 6 million dollar market cap doesn't mean it would take 6 million dollar market buy.
In a bull market this is nothing.
However, to bring the price to 0.43 cents on Probit you don't need 40K $, or as you say, 45k$ to bring it to 0.50 cents.
Right now to buy the entire sell order book on ProBit, you need $18,163 and the price touches the price level of 0.43 cents. For a total of 42k INN sold.
and to sell the entire order book and get the price to 0.008, only $15 is needed. for a total of 1997 INN traded.
