Crypto investors talk about how decentralisation will benefits all but all I saw is how cruel decentralisation in crypto space can be, hacks and theft have make decentralized projects the perfect target.
If its centralised there will always be someone to take the blame but that's not the case with decentralised projects
1. The team will easily blame the hacker, even if its an inside job.
2. Any form of reimbursement isn't going to happen.
We all want decentralise but it deals more damage to investors than centralise, the only thing decentralise does better is freedom but that freedom is also a huge weak point.
There are pros and cons on both sides. You mentioned about some disadvantages of decentralization, but skip its advantages. You will not see inside manipulation or misuse of power a decentralized environment. Centralized environment just takes away your freedom with unreasonable regulation. Like India implement a 30 % tax on all crypto gains. This is a threat to crypto.
Yes, there isn't a perfect system without flaws. Centralization theoretically has good points, but on practice they are almost inexistent. We can easily see this by how decentralization was broadly adopted by many people around the world since bitcoin was launched in 2009. They did it because the centralized system wasn't fulfilling their needs and demands as individuals, otherwise there wouldn't be any reason to adopt bitcoin and so many other products the decentralized crypto market offers. I believe to be extremist isn't healthy, so we need to find a balance between centralization and decentralization in order to enjoy the best both systems have to offer.
