A strange statement for an erudite man. From the definition of fiat "Fiat money is a currency that the government positions as a legal meant of payment, but it has no internal value, isn't provided with reserves." That is, we can draw a fair conclusion: they are provided only by the promises of our government and nothing more.  But I don't believe the government.The governments don't like cryptocurrencies because they can't control it, unlike the fiat cash,which they can print on the first need.

OMG so sad to hear this news

Hi, first of all we need to comprehend what he meant by "fling". This fling that he refers to is the current hysetria amongst investors who have least knowledge abt the technology involved and are only concerned with the huge profits which suddenly bombarded the traditional financial sector.
As per the report from Mangrove Capital on 200 ICOs revealed that ICOs provide an ROI of 1,320% as compared to 7-10 % in stocks. People like Eisman didnt have much option apart from stock trading before crypto currency hence its his new Girlfriend/fling.
Now coming to your question regarding what is the intrinsic value of crypto currency ? You can refer to as what was the motivation behind the inception of Bitcoin and Ethereum. Vitalik and Satoshi have already pressed upon the reason to provide financial freedom back to masses rather than leaving the power hold of finance/economy in a few hands.
P.S. - sorry for the long reply.

I don't see that news as bad news for bitcoin at all. Somehow as you interpret it, but what is the impact one person can make against millions of people about this bitcoin. I don't care if he's a famous person, all I can say right now, bitcoin is still okay.

I think the usual bad news in bitcoin is the lower market value it haves since many investors want income but for the new investors they are glad since low market value it have in the market.

it has been a long time since we dont see bad news about bitcoin, so how is it possible? i think that there is no way at the moment, STOP with the fud because it makes no sense

For one months we are always found bad and negative news about bitcoin and crypctocurrency, why is happen and how long will be bad news about bitcoin ? many investor was afraid because have faced bad news about bitcoin and make bitcoin price more lower than usually price. many investor keep and run away for invest their money on bitcoin because bitcoin price was low. we have protect and give support for cryptocurrency to recovery their price to be higher.

He did not see the long-term potential of Cryptocurrency. The top 50 currencies are operating and making very good profits from their business model of money transfer. In the future, banks must link with altcoins to be able to improve their money transfer services. I believe in the good future of the Crypto market and don't care about Steve Eisman.

Well, at this stage we must understand that Bitcoin or the Crypto industry is still in the basic phase of development and hence we don't see the high volume of ground-level usage of cryptocurrencies. However, the value of Bitcoin is increasing day by day as more and more merchants are getting involved with cryptocurrencies and accepting it as a payment system. It is true that we still have a long way to go but I am optimistic about the potential of Bitcoin and Crypto industry.
