While I agree this "could" happen, I think its highly unlikely for a company in very early phase to buyback extreme amounts of stock. It would require a decent amount of capital that could be used for growing revenue.
Yes, I’m sure the perpetrators of this wildly successful share selling scheme will step up and contribute all the millions of dollars earned from selling shares and do a MASSIVE share buyback.
Bear in mind that the ENTIRE MC is a little over $1M—so the buyback and retirement of, say, 100M shares would cost around $100K. NOT wildly improbable during the remainder of 2019, imo...
