Time to get real. If your blockchain:
* Has a CEO
* Contains pre-mined tokens
* Distributed tokens via an ICO
* Can execute a forced hardfork
* Doesn't use a consensus algorithm
* Can be changed in a short time.
...then it's most likely centralized.
It is more of the coins than you think. Take for example Ethereum:
* Executed a forced hardfork
* Has a central point, Vitalik
* 20℅ of the coins were pre-mined
It follows logically that Ethereum is centralized.
Here are the proper decentralized crypto blockchains:
* BITCOIN
* LITECOIN
* MONERO
I'm a hardcore ideologist more than an investor, but the upside of having a blockchain that leaves central banks utterly incapable of taking control of your blockchain is that they are probably the most fundamentally economically viable too. That being said I still think Ethereum, Dash, Ripple and Cardano plus a handful of others are great coins, but for different and interesting reasons.
When it comes to distributed ledger solutions remember that Blockchain is Open Source so any back-doors can be identified and nobody can own the source code.
