If there are vulnerabilities, maybe inform legit people of them so they can try to repair them, instead of running some new scam?
People should be afraid of POS. It is at a very fundamental level no different from Apple, or a wall street bank, without the safety net provided by the government regulators. POS is a bad emulation of wall street. POW is a good emulation of gold.
Edit: This is not as simple as a code vulnerability that a dev can fix. It is very fundamental.
POW is less safe than POS, because all you need is over 51% mining and you can double spend .
Miners start dropping off as POW mining no longer keeps their profit margin high enough.
POS miners profit margin to stake does not force them to shut down like a POW miner.
If all of us trust government , there would be no cryptocoins.
Cryptocoins exist because less people trust their governments everyday.
