no, cryptocurrencies are not centralized. I don't think that's out of the question . But sometimes countries and large companies can create centralized cryptocurrencies.

I don't see anything. It's a feeles and near instant eco friendly currency. The decentralization is guaranteed by different nodes run by voluntary aktive users. The giant price rise in 2017 was because of the hype I think but as I can see the price has commuted itself. I hope I could help

It's just like bitcoin in its early years, many people aren't open to new ideas, just like bitcoin is better than fiat money, NANO is better than bitcoin.
And NANO is already more decentralized than bitcoin.

Nano is a lightweight cryptocurrency that is designed to facilitate secure, practically instant payments, without fees, and addresses some of the major limitations of both legacy financial infrastructure and many modern cryptocurrencies.

It is a peer-to-peer platform that uses a unique block-lattice data structure to allow users to easily transfer value to one another without relying on centralized intermediaries.
Development of the project began in 2014 under the name RaiBlocks, and the coin (then termed XRB) launched the following year through a public faucet, which allowed users to claim small amounts of XRB after completing a captcha challenge. Users were allowed to complete as many captchas as they liked to increase their words — effectively trading their time and effort for XRB. RaiBlocks (XRB) was rebranded to Nano (NANO) in January 2018, with the new name chosen to better represent the speed and simplicity the project offers to users.
I hope this solves your query

About the spam query simply put, Nano uses PoW (like in mining bitcoin) purely as an anti-spam measure. PoW makes it take some amount of time and energy to send a transaction, which is generally unnoticeable for someone like you or me who would send a few transactions here and there. For an attacker, it would be too costly to just infinitely spam.
It is similar to the concept in Hash Cash, which was used to prevent email spam. Of course Nano's implementation gets a lot more complicated than that explanation with more factors to keep in mind, but I think the explanation works on a simple level.

About the mining question - there is no mining involved compared to a PoW coin such as Bitcoin where each block is mined and put in a serial main blockchain. Since there are no fees with nano, there is no monetary reward system for validating transactions and thus no emergent centralization due to economies of scale. The reward is a decentralized, ultra-fast, feeless, green, secure, scalable and robust system you can use how much you want.

Finally I would say BTC will be an investment, like gold.Nobody will actually make purchases with it. $nano will be used due to speed and zero fees.

I think the biggest concern for any person looking into various alts is volatility but in Nano's situation they have a proven track record, a strong dev team and they boast a feeless/ instant way to transfer currency. The heavy fees associated with coins like bitcoin make their use as currency unpractical. There is only room for growth In an atmosphere where block subsidy's and transfer fees are so prevalent. Its a matter of time before more and more people get on board with what Nano is doing(some major corps are showing interest in Nano). The instant transactions are a product of Nanos efficient block chain coding which makes it possible for people with older hardware and out of date systems to be able to transfer and swap Nano as well consuming a fraction of the energy other blockchains consume.

Nano crypto money has set out with the digital currency mission for the modern world. You can send it without using a digital cryptocurrency that you can make without making transactions with the nano wallet (wallet).

Nano network comes up with a cryptocurrency feature that combines speed and security in payments, and is widely used and widespread. Unlike cryptocurrencies like Bitcoin, it is environmentally friendly when it comes to mining.

It seems that many cryptocurrencies are insufficient to be used in daily life. The number of supporting transactions per second of cryptocurrencies such as Bitcoin and Ethereum and the blockchains of the algorithm they know are congested. Therefore, it seems suitable for daily payments. NANO is ready to be used as digital money with 0 transaction fee.

Nano developing by seeing Bitcoin seems to be successful. The justification is that this digital currency, which has changed algorithmically and is superior to the modern world, offers a reliable blockchain network for money storage, except for payments.

I think the performance at mining coins of domestic people need to be improved. Many people who wants to enter to the world of cryptocoins and web 3.0 services haven't the high level gear and knowledge, in that case, mining is centralized in terms of technology and equipment. With the adoption of Nano coins, people will want to enjoy all web 3.0 services with the plus of getting a reward in their Nano wallet.

I believe that the nano is undervalued, the situation with bitgrail unfortunately helped

cryptocurrencies are centralized. I thing it 's Future

Directed Acyclic Graph or DAG is a method of confirming transactions without having to rely on miners, because every time we go to make a transaction, we have to confirm other transactions as well. Transactions, which will make coin transfers faster and cheaper than using a conventional blockchain, for example coins using DAG: IOTA and Nano

This criptocurrency isn´t centralized, and energical consum transfer is lowest than bitcoin

because you can't wait to collect.

A centralized cryptocurrency exchange is a platform where you can buy or sell digital assets. Here, you have to trust a third party to monitor the transaction and secure the assets on behalf of the buyer and the seller. ... In most cases, centralized crypto exchanges provide their users with flat pairs at stable prices.

Nano is a good cryto just like bitcoin that grows from time to time

Nano emerged to solve the problems of today's cryptocurrencies. Mainly, low scalability (few transactions are processed per second), high latency (due to low scalability, transactions take time to be confirmed) and energy inefficiency (bitcoin mining consumes more energy than 159 countries use in a year) .

To solve these problems, the Nano blockchain (XRB) works differently than other cryptocurrencies. In XRB, a structure called block-lattice is used, where each account has its own blockchain to store the balance and transactions. Of course, only the account owner can carry out transactions.

With a blockchain for each account, updating when a transaction is made is done in real time and asynchronously. To transfer money from one account to another, two internal transactions are required: one to withdraw the amount from the sending account and another to add the amount to the recipient's account.

Transactions are verified by an anti-spam tool that consumes much less processing power than bitcoin's proof of work (PoW) model. It checks only a few basic requirements, such as whether the single transaction has been done before, whether the block is signed by the account owner, whether there is an account opening block and whether the transaction is valid, following some specific criteria.

Using less processing power and with some optimizations in checking transactions, they are confirmed instantly and at no cost. In addition, scalability is unlimited, as the cost of validating each transaction is very low. Today, the Nano network has processed 4.2 million transactions with a record of only 1.7 GB.

What is Nano for?
Nano's main objective is to be a high-performance cryptocurrency. “The Nano protocol can run on low-power hardware, allowing it to be a practical and decentralized cryptocurrency for everyday use,” says the founder, Colin LeMahieu, in the document that founds the virtual currency.

no, we can't find flow of bitcoin transaction . so it won't be centralized by government

A nice app for nano

Yes

Idk

Nano is an affordable cryptocurrency focused on widespread use as a means of payment.It uses a grid structure of the network, unlike Bitcoin Nano uses a partially distributed registry, since the data about the blockchain is located on the accounts of users and each of them monitors it independently.That is, the user maintains the functionality of only his account, and the transaction is visible in the blockchains of the recipient and sender, as two separate blocks. This allows you to significantly increase the speed of transactions, remove fees and use a light protocol, without the need to download the full blockchain of the network.
