As far as I know, the price is set in ETH and will remain as such even if the ETH price changes. You will receive 27000 GRAIN for 1 ETH.

Appcoins has been listed in Binance. All the ICOs wish their coins is listed in binance. But they cannot. Appcoins was listed in binance on the day tokens released.
Do not try to find a better exchange. Binance is the best.

Carry cash physically?
It's ling time this problem has been solved with the help of credit cards and also debit cards. I don't think any one use money in form of paper for big transactions.

I agree that many projects will fail. And I also agree that friendz won't replace facebook.
But it's a good idea to use blockchain technology for a social media. What's the problem?

It is what is shown in charts. The price was falling sharply. After rising to 8000 dollar, there is a strong resistance which don't let the price to fall. Also there is no FUD now.
Many people had believed that the price will rise again. But the time of rising wasn't known. I think the time of price rise is coming.

Nothing can do. No other option than keeping them in the wallet as usually the transaction fee is higher than the tokens value.
I also have some worthless coins and there is no hope of rising prices. Because they are not listed in exchanges.

There isn't something in the world called "National cryptocurrency" and it won't be. If a government wants to create its own cryptocurrency, there is no doubt that the government wants to control it.
If a currency is controlled by an authority, it is not a cryptocurrency. Cryptocurrency is something like bitcoin which is not controlled.

You shouldn't compare bitcoin with a potato.
If a potato price reaches 10000 dollar, I won't buy potato any more. And note that a potato will never reach 10000 dollar. Because there will be no demand at very lower prices.
You should compare bitcoin with something else like a house. You need a house and you have to pay for it. If a house becomes very expensive, then you will buy a smaller house.

Big house = bitcoin
The smallest house = Satoshi

There are many people who sell their coins after the prices fall. These people buy after the prices rise. If they buy and then the price rise, they don't sell their coins. They wait for the price to rise more. These kind of people finally sell their coins at a price lower than the price they have bought the coins at. They are always losers.

Don't panic. Wait.

No government has officially accepted bitcoin or other cryptocurrencies. Also, medias are negative about bitcoin. We usually don't see a positive program about bitcoin on TV. Advertisement can be very effective. But there is no positive advertisement as governments don't want it.
Most of the people in the world do not search about cryptocurrencies. They judge about it only based on what they hear.

Price changes is not related to bitcoin death. It is related to market and manipulations by whales, news, rumors, etc. People use this opportunity to make profit. If you had sold your coins at high prices, you had make money. But seems that you have not sold them. Now you should wait until the price rise again. You shouldn't sell your coins when you are in loss.

But in this way, people miss a big opportunity. There are a lot of advantages that are ignored by the government. It's not a good idea to ban bitcoin to protect people. Instead of this, the government should help the people to know cryptocurrencies better. Banning a technology won't help people.

For sure Bitcoin is a very good investment now. When bitcoin price was 18000-20000 dollar, there were many people complaining about the high bitcoin price. They wished they had bought bitcoin when it was cheaper. what is happening now is exactly what those people wanted.

Yes, Governments have no control over bitcoin. If they had control over it, they had killed it before. Now they are only trying to make some rules. Also, some governments are trying to make the people uninterested in bitcoin. That's all they can do.

I think it depends on other countries. Most of the countries have not ban bitcoin. But there is no rule for bitcoin.
I think China is waiting to see how other countries will decide. If other countries accept bitcoin, China won't miss the opportunity and will allow the citizens to use it after the rules are made.
For now China think that bitcoin can be a threat for its economy and don't risk.

Cryptocurrencies are not still very popular and most of people don't know crytocurrencies completely and that's why people are using fiat money. Better to say people have to use fiat.
Banks are worrying about the future. When all the people will know cryptocurrencies and cryptocurrencies will be used everywhere.

Bitcoin can be used as a currency. But there is no doubt most of the people know bitcoin as an asset. Just look at the threads have been made in this forum. Which one is being discussed more? Most of the people are talking about price changes and holding. I personally want bitcoin to be used for daily buys and sells. But I am holding bitcoin. I have invested in bitcoin and I am waiting for the price to rise.

Yes. But it's an advantage as long as it is not used for illegal purposes. It can be a disadvantage too. Criminals can make transactions easily without the possibility of being tracked.

The demand will not rise once after the the hardware is made by Samsung. But such good news can affect the market in long term and even in short-term. Samsung is not a small company. It can bring many new people into the market.

The price is volatile and it is same as stock market and Gold. I don't think It is forbidden for them to invest in Stock market or Gold. There are many financial activities that they are involved in.
