It is a machine on which you can trade fiat for Bitcoin (on some even Litecoin and Etheteum) and vice versa. You have plenty of tutorials- guides on how they are used. Basically, you put in fiat and scan the qr code from your phone so the machine can send Bitcoin or send Bitcoin and when the transaction is confirmed you can use the reciept you get to withdraw the cash. Many people say that the rates are innacurate, though.

It is just instinct, people are afraid of losing money so they panic when the price is going down. You just need to keep calm and know that it will rise back up even stronger, but you just have to wait and be patient. If you plan on profiting on long term, buy low and just forget about Bitcoin for a while, when you check in you will have a nice surprise.

Why would cryptocurrencies reach zero? It couldn't just drop without any reason. But seeing as most of the alternative and new cryptocurrencies are dust, they are now pretty much worth nothing. The only ones that are worth something are Bitcoin and Ethereum, Litecoin and a few others. Below are just attempts to make competition to Bitcoin.

Just shiw them your or someone else's earnings or stuff you bought from investing in crypto. If they still hate on Bitcoins, just let them be, they will miss out a big opportunity and will regret when Bitcoins price pumps up and then you can show them more money if you make some, they will surely be angry and maybe even try it out or at least shut up.

If bitcoin could reach almost $20.000, it can surely go up more than $9000. It is never late, Bitcoin is always going up in long term, so don't be afraid to buy it at the current price, it is going to be at least $10.000 this month, just be patient and don't panic, you can still make a good profit if you wait long enough.

Those people are probably people who didn't have money for Bitcoin so they bought Ethereum when it had a small price and now they are waiting for it to overcome Bitcoin so they could make a huge profit. Others are just trolls or just hate Bitcoin for some reason or no reason at all.

Nobody thought that the transaction fee would go down, but I knew it! I was scared, though, I thought that it would need a lot of time to go back to normal, but that didn't take so long. I just hope Bitcoin will stay like this, stable, fast and almost free transactions. The future is here!

Very sad indeed, in my country Youtubers make thousands of dollars, yet there are no jobs for people that have degrees on university, faculties. Even if free and easy money seems awesome, I would be much more proud of myself if I earned it by sweat and blood.

It is just what cryptocurrencies are, they can't have a fixed price. They are always volatile, the price can only be stable but with minor oscillations and that is for a very small period. I think cryptocurrencies could only be stable when they reach the maximum supply, the price would probably be huge but at least it couldn't go up anymore untill the currency crashes and dies.

That is great news and everything, but Samsungs goal here is to make money. They don't really care much about cryptocurrencies, they saw that graphic cards and mining rigs are expensive yet people buy them a lot and that they can make a lot of money by making mining chips.

People who think Bitcoin is bad because it is used for illegal activities are quite dumb. Cash is also used for illegal activities yet no one says fiat is bad because it is used by criminals. It wasnt supposed to be used that way, but it is good for criminals because it is anonymous but that doesn't make Bitcoin bad.

Most of the people say it is not because of "high fees, long transaction confirmation times", but thats outdated news, Bitcoin still has a higher fee than it had a few years ago, bit the transactions aren't very slow right now. The only problem right now is adoption, more stores and sites need to accept Bitcoin, and then it will be perfect.

We might have digital money, but it wont be Bitcoin or any cryptocurrency at all, it will stay fiat, but only on credit cards and in digital form on our phones and computers. Every country is going toward doing this, and cryptocurrencies wont be an option because the volatile price, the fees, decentralization.

Buying bitcoins is less of a hastle and you don't need as much as money as for mining, but it is more risky than mining. You might lose money when the price drops, while when mining you will be sure to get your money back. I would rather mine, but if I don't have enough money for that, I would buy.

It can't be more popular than fiat currencies, but it needs to be more popular. Bitcoin got most  popular when it reached the recent all time high price, many people got interested and even non-users gained knowledge that Bitcoin exists. It wont get much more popular unless it reaches a bigger price and the social media  banning crypto ads aren't really helping.

Bitcoin sure is falling really fast, but I don't think it will fall that much, that would be a too big decrease. If it would fall that much and stay there, I would consider leaving this. Bitcoin was 10.000$ recently and if it just falls 10 times the price it would be outrageous. I think it will stop above 6000 (and I hope it will).

I am not worried a lot because I think Bitcoin will get past any challenges and problems, it always did in the past. Of course, you should be worried because you invested money, but I think Bitcoin will stay stable for a long time. We had transaction problems recently, and everyone thought that Bitcoin is dying, but here it is, up and going very stable.

Well, all cryptocurrencies have volatile prices, and they can't ever be fully stable. The price can be stable at some point, but there are always small oscillations, a few dollars up or down. This is how the price is and it can never be stable and it is a good thing for investors and Bitcoin is mainly used by them.

Pretty much all posts there are scams and mostly are those kind of posts like doubling Bitcoins and similar. Those people double your Bitcoins if you try with a small amount, and then they gain your trust and when you send a big amount, they dont pay back. I never try those sites and I always send negative trust.
