As i understood of my former stock market experience, buy back is just for increasing artificially the price of an asset. It is just like a snake bitting its tail : that will end badly.
Healthy company never o this as it is  clearly not an investment but just a speculative tool.
What they are doing is clear : speculation instead of investment.
They should have better cut off in the distribution rate, then using this fresh money to invest.
Instead of this, it is just another disguised bump and dump scheme.

In other word, just a smart move to fool the younger and inexperienced crypto fan.
