There are 2 sides to the crypto coin, Centralised crypto and decentralised crypto.
Surprisingly, decentralised crypto has some downsides, and centralised crypto has some upsides (In this article, I am not saying decentralised crypto is bad; I am just showing the arguments that prioritise centralised).
Firstly, decentralised crypto means that if someone steals crypto and transfers it from one wallet to another wallet, that is usually irreversible, and the crypto will be lost to the bytes of time. Whilst centralised means that you could theoretically contact support, prove ownership and get the transaction reversed.
Secondly, it can be less secure; if there is a vulnerability in the software, someone needs to patch it and convince/get the majority of users to upgrade to the version.
There is an example in one of the world's biggest cryptocurrencies, Bitcoin. On August 15, 2010, a Bitcoin block was mined that minted over 184.4 billion bitcoins - this was due to an overflow bug where Bitcoin had an integer rollover, leading to the Bitcoin cap being broken.
This was rolled back 5 hours later to fix the bug.
Luckily, since Bitcoin was a small and active community, the update was quickly adopted, and the bug was solved. Imagine what would happen if the bug wasn't patched? There is a high likelihood it would stamp out Bitcoin's chance of success.
A centralised crypto would be able to easily fix the issue since they could just update their servers.
In conclusion, both are very good, but there are a few small disadvantages to decentralised crypto. Do you think it is worth the risk?
