Sergey was the developer of another coin similar to link 5 years ago called NXT. it was pumped up over $1.70 and is around $0.017 today. Bitcoin's founder vanished also but that was a good idea so the price has risen sharply since.
Proof of Work makes much more sense than Proof of Steak because you need to reward people for securing whatever coin you want to store value in.
Decentralized is better than Centralized, something centralized can be shut down where as its not possible to shut down something decentralized.
A good example of that would be limewire,kazaa,napster because they were centralized they eventually got shut down, decentralized versions like bittorrent proved unstoppable.
Link is still pretty much an unproven idea and a bad one In my opinion. its centralized and is planned to be Proof of Steak. Its also private rather than open source which should be another red flag. Open source is more secure because anyone can read the code and submit improvements/fixes.
There will always be people that buy coins of no value, shill them on sites like this then dump making themselves a good profit at the expense of others.
If you are on this board looking to make money in crypto I would recommend buying bitcoin instead, mining some place with cheap electric, or just do arbitrage buy the same coin on a cheap exchange and sell right away on the exchange where that same coin costs considerably more.
Lets have a sensible discussion instead of pumping shitcoins.
