I am surprised after a few comments I am going to be the first one to disagree with what OP says because he bases his reasoning in a false analogy:
There is always a comparison among Bitcoin and Gold investment in the market but we are ignoring the fact that gold is centralized assest but Bitcoin is decentalized source of investment backed up by Secure network of miners always.
That comparison is wrong. Both are decentralized.
The government has full control over your gold investment and any time they can ask you to deposit it with them or even put a limit to gold holdings with individuals which is another concern but still you can't speak being residents of democratic countries.But Bitcoin provides your freedom to enjoy your funds according to your own wish without any centeral authorities intervention because of its decentralized nature and moreover it's network is always secured by the miners.
That's again wrong. Gold is as decentralized as Bitcoin. The value of Gold doesn't come from a Central Bank, unlike in the case of the value of USD, which comes from the FED and the US government. Gold is valuable because people believe it's valuable, the same as Bitcoin, they don't need a Central Bank or a Government saying that they are valuable.
Other than that, the government can confiscate your Bitcoin just like they can confiscate your Gold if they make an executive order for Bitcoin like they did in 1933. Is it a little harder to confiscate it? Yes, but it is similar. If such an order were passed, all Bitcoin from centralized exchanges would be confiscated by the government, and in the case of people who keep Bitcoins in hard wallets it would be more difficult but just as it was difficult to confiscate gold from someone who had a little bit of it hidden at home.
You can use Bitcoin as both investment assest and to make payments to other people by making transactions with very nominal fees over the blockchain.
This is also false. Gold is both an investment asset and you can use it to make payments. It's not so usual nowadays, but you can, and it has been widely used to make payments throughout History.
So why are we making such comparisons?
Why are you?
We need to understand the importance of Bitcoin in regards to other financial assest as Bitcoin is only decentralised currency that can provide you freedom from these traditional monetary system and make you king of your own money.Invest in your future.
Bitcoin nowadays is not a currency and it's not the only decentralized asset, as I have shown.
