BTC is there for the transaction of money over the internet, and to some extent, fiat cannot be replaced. Does not matter how much we want to revolutionize the world with cryto, some parts will always be underprivileged.

Now a day’s digital currency are growing so fast. So I think there is possibility that btc can be the money of future and stop depending on fiat money because People can use it securely without any permission.

Decentralized crypto currency is not related to conventional currency and therefore will not depend on it in the future. At the same time, it can not replace the existing national money and can exist only in parallel with them. In this case fiat and crypto currency can complement each other. States will not take decisions on the transition to a decentralized crypto currency, since this will have a very negative impact on the economy of any state.

Yes, if bitcoin will develop it would be possible. This requires that bitcoin has a much larger capitalization than now. Then what happens is what you write about

Cryptocurrencies will certainly replace fiat money sooner than you think
Cryptocurrency is disrupting the financial system because it has quite a number of advantages over the conventional currency such as the dollar. By eliminating intermediaries, digital currency gives you more control of your finances. Besides, it can be used as a hedge against the inflation of the dollar. Most cryptocurrencies are also extremely secure due to the use of dual-sided cryptography for every transaction. Bill Davis, a public sector Digital Strategist & Design consultant, says cryptocurrencies use hashing to effectively verify the integrity of data by systemically representing large amount of data as short numbers that cannot be replicated.

Unlike fiat currency, cryptocurrency cannot be debased by any government because it’s not tied to it. Even the governments cracking down on it are actually making it more valuable. Fiat currency can become worthless when a government gets replaced or falls apart. And it goes without saying that no government is immortal.
 Blockchain may still be in its infancy but the best case scenario is a global financial revolution. Fiat currency is a system that heavily relies on debt, and that system is failing everyone who isn't a bank. Most crypto projects are still in their early stages of development and still have years before they can prove their uses, but when they do we really could see the largest transfer of wealth in history.”

It seems we’re hesitant to accept that cryptocurrency is quickly becoming a new kind of money. In essence, Bitcoin is already miles ahead of the dollar. Right now it’s worth thousands of times more, yet this is just the beginning. What’s even interesting is the colossal number of people who have never heard of it or those that just chose to ignore it. However, it’s a matter of time before more people jump on the bandwagon.

User-adoption is a legitimate challenge facing cryptos today; nonetheless, all cryptocurrencies are still in their infancy. It’s pretty much like the internet in the 1990’s. During its early days, the internet was only used by nerds. A few years later, it saw rapid acceptance and adoption. Now, we all live on the internet. This is exactly what will happen with cryptocurrencies. So, it’s just a matter of time before the rest of the world catches up with this technology. cryptocurrency holds a long-term promise owing to their fast, secure and efficient payment system. Ramson says cryptocurrencies’ innovative ideology for a more secure monetary future will be the key driving force behind their adoption as a payment method. so ofcource in no distant time bitcoin will definately be indepenend of fiat. Regardless of how governments or investors feel about the impending switch from conventional currency to digital forms of currency, the wave of change is unrelenting.

If you are asking for personal opinions then I think it will coexist with fiat currencies rather than totally replacing it. Just like how credit cards and debit cards work right now. So, ultimately it will have to rely on fiat no matter what happens. The reason behind this is because we have been accustomed to fiat so much that we find it difficult to replace it with any other currency.

I think bitcoin will still depend on fiat money. Because to buy or invest in bitcoin we need fiat money, maybe just that. I think bitcoin will coexist with fiat currency, because not only  bitcoin which is needed by many people, butz fiat currency is also needed in everyday life.

Till now Bitcoin still rely on fiat currency but bitcoin will be an alternative for payment using fiat currency. If we wish for to make payments in realistic situations, we will use bitcoin.

Bitcoin is not really dependent on fiats, the dollar or euro value of bitcoin is just the simplest way we can relate to value goods and services which often are outside the crypto world
