What is the reason of huge pump? It is insane to see it pumped from 40k sat.

Actually, what was insane is how low it had sunk until recently.
The coin had been steadily falling in price throughout last year for no real reason in spite of all the active development.
Half of this "pump" is actually a massive, long overdue correction. The other half is probably for real news or simply buyer frenzy from people trying to jump in the bandwagon.
No surprise if it corrects again (to around 0.01 perhaps) and people start crying dump and scam because they lost money in their gamble
