The only one detail in BTC that makes me thinking is a scam

[Coyster]

The difficulty will always increase and never goes down?

The bitcoin/technology behind it, has somewhat gone mainstream thus an increase in the difficulty of mining,this is to ensure that transactions are effectively confirmed,and also eliminate a breach..
Miners will continue to spend money to mine,as they are rewarded handsomely for it

And what will happen when all bitcoin will be mined? How will confirmation work then?

It's not going to change anything,as miners would still be the ones to confirm transactions,only that they then wouldn't be rewarded with bitcoins,but solely transaction fees..

Ahahaha you just put concrete to my statement, difficulty is another argument how easy was in first 2-3 years to mine 10mil bitcoins by small groups of people, when nobody knew about mining, only in 2012 people waked up and starting to mine. By that time, half of bitcoins where already mined, imagine what will happen if they decide today to sell 3mil bitcoin, where the price will go? And still they have another 7-8 milions of bitcoin mined for free almost.

Bitcoin wasn't mined by a few individuals as you think, many people mined them and they have spent them eventually, so those 3 million were spreaded upon a lot of users. Nobody could have known that Bitcoin would get anywhere, and if it were a scam, the holders of those millions would have sold everything long ago.

Let say bitcoin price will reach 2000$, what will happen with miners? Will they afford to still pay electricity to mine it? And yes, is very strange the way bitcoin is mined now, with a lot of equipments who cost large amount to mine bitcoin. The difficulty will always increase and never goes down?

And what will happen when all bitcoin will be mined? How will confirmation work then?

Miners are a dynamic entity, they can shutdown anytime they want their rigs, difficulty also will react dynamically , so, price can go to 10 dollars, miners will react acordingly, they shutoff they rigs if is not profitable for them. But will never shut down all in the same time, it's a dynamic entitity. Me, i can use  bitcoin same way at any price whatsoever, problem is that e-commerce industry cannot join this electronic cash system because of volatility. As the guy says earlier, manipulation can last forever, as long as 10mil bitcoins are owned by some small groups of people. If bitcoin goes to 100k, they still have 10mil bitcoins and they manipulate prices at any point in future.

OP is forgetting that the 10 million mined that he's talking about was sold and redistributed among other people. People who mined 1000 bitcoins each very rarely are still holding. Their coins could already have thousands of users if not more. Also, we don't know the number of lost coins, we can only estimate based on the coins that aren't moving. My coins didn't move for 3 years, are they lost?

Too bad i deleted my list with 2 mil bitcoins that was mined from 2008 to 2010, that was not moved from wallets, why you are so sure they sold ? Maybe they just split wallets. Hard to believe they can sell for fiat so many bitcoins.

Mining has more function in the space than just producing bitcoin. So mining will be demanded however it has not been as profitable. Mining volume and quantity per time had also reduced with the high percentage available. The percentage of bitcoin in the past year involved more of the team than in the recent

The ones that mined 10 years ago are unlikely to still be in possession of those coins, they will be spent or lost in a landfill. Only satoshi still has his old coins but they aren't moving

Maybe Satoshi's coins are in landfill also! Just because we can see them
doesnt mean they are accessible, the private keys could be long lost.

@OP just because there were early adopters and they were rewarded or
bought very very cheap coins doesnt mean bitcoin is a scam. Buying
bitcoin today could also qualify you as an early adopter when you look
back in 20 years time, its all relative

Really? During big moves there's 5000 Bitcoins being traded on Bitstamp every hour. Do you believe that it's difficult to sell large amounts? Think again. There are bigger exchanges than Bitstamp with more trading volume. Traded coins have to come from somewhere. It's not the same 1 million coins being traded over and over.

Well they were the first to believe in Blockchain. They're entitled to it. I'm sure in some years to come, those holding Bitcoin now especially if the price rises a lot will be deemed to be among the scam?

Every detail of bitcoin can be thought to be a scam, I mean all this game with so much money. But bitcoin all this time is there and never went out or it did not exist anymore, but when the snake bites and the beetle is afraid, so with people if somebody is deceiving them, that is why it comes to fear
