Bitcoin is a Bubble

* There are only a limited number of coins out there so people are going to stop mining for them as he near that limit. You can see that now with fewer people buying ASIC and similar FPGA modules.

* The transaction fees are getting be as great as the cost of a pizza transaction

* Lost coins - There are millions of wallets out there with people exploring BitCoin that has just been lost. Its a lot easier to lose your wallet hash then your physical wallet.

Do I think block-chain will take over? Yes and then it will crash spectacularly. I honestly look for the markets to take off over teh hype and then die death crashing into a universal central system.

Look for more slow downs with chat-bots, games, and video services, onion routers piggy backing on the service. Then there purposely bad transactions in DOS terrorism to destroy confidence in issued currency. Eventually this will force the 'new banks' take us back a world centralized bank with sharded nodes that a UN like structure will control.

* The limit of coins will increase the value of each individual coin (deflation), while the USD's value will still inflate. For miners this doesn't have to be a problem in the long term, since money can still be earned on processing transactions.

* The problems with high transaction fees and slow transaction times will hopefully be solved with the Lightning Network. I know people have been working on the Lightning Network for a long time, but I truly believe it will be introduced for Bitcoin in 2018, because there is a huge need. If Bitcoin will not adopt the Lightning Network by 2018, perhaps some other crypto currency could take over as the number 1 crypto.

* Lost coins will push the value of the existing coins higher.

Do I think block-chain will take over? I do believe so. We should take a very good look at Asia, I believe the most important developments regarding blockchain tech will happen over there. One of the projects that is of great interest to me (I've bought some coins) is Omise GO. Omise GO could give banking capabilities to people without needing them to sign up to bank accounts. It means people without bank accounts might be able to purchase products over the internet using their Omise GO wallets. It also means people can receive money easily without needing a bank account. Asia still has a lot of people without bank accounts. Of course many other interesting applications with block chain tech are developed as well. For example software to track inventory for shipping companies like Maersk.

If some important economy destabilises, look for more common people move into crypto as trust into central banks erode as has been seen already in e.g. Venezuela and Zimbabwe. I believe this could happen in the Eurozone as I believe the Eurozone's economy is still very weak and a small event could evolve into a big crisis over there.

Look for increased efficiency in the block chain and decreased power of governments and banks in the longer term future.

- How does Omise GO provide the most important bank feature: borrowing money? After all that is the main source of bank's income & impact on economy.

You have nothing to lose by making such predictions, just like how everyone who predicted the rise of tulips is now laughed upon. Furthermore, even if Bitcoin DOES go up, it's not like you'll be applauded for being an 'oracle' just because you predicted this either. Pretty much everyone who's invested in Bitcoin, hoping to get rich, and doesn't understand the technology is saying the same thing.

Why not actually learn how the technology works, so that you don't make these shallow deceptive remarks that sound exactly the same as the conversation I had with my blockchain-entrepeneur friend last night, and instead maybe stop trying to get rich quick by hyping Bitcoin?

Regarding all the reasons you pointed out, except for the Lightning network solution, the rest are really big problems. Just because more and more people buy Bitcoin you think it will go up to 100.000? Just because you have some Bitcoin because of your speculative greed, you think Bitcoin will go up to $100.000?

The limit and distribution of coins are really the biggest issues right now, and there are tons of different approaches people are working on to keep it that way. Just like tulips were unfairly distributed and overvalued. I'm sure people will see through the get-rich-quick scheme.

One thing I find annnoying about Cryptocurrency enthusiasts saying Bitcoin will grow is how they think Bitcoin is some evolving thing that's sure to succeed because they bought into it early. Bitcoin was designed to enable people a decentralized currency and that's the whole point. People will find various ways to lure people into buying Bitcoin (or Omise GO) without clear benefits because financial inventivization comes from them already owning some coins.
