In Fiat Interest and Inflation cancel each other and promote borrowing and thats a healthy thing, but bitcoin economy a borrower has to fight against deflation and interest, if interest rate gets lower to zero then lenders will have no incentive in lending
At a basic level, the person providing the loan hopes to receive a small return (interest) for providing the capital, and the person receiving the loan hopes to use that capital to make profits in the short term.
Removing inflation from the equation (eg by providing a BTC loan) does raise the bar for what could be considered a profitable venture for the loan taker, but that does not mean every loan will no longer be profitable. Rather, it just incentivizes individuals to seek out ventures which have a higher chance of turning more profit.
In my opinion, the argument of "nobody will spend a deflationary currency on anything!" is silly. Individuals will still have to spend, they may just have a higher threshold for the question of "what is worth buying? (or investing in?)". Even if your money is deflationary, you'll still have to pay rent, because its better to have a safe place to live than to have a little more money in the future, but nowhere to sleep.
Further if somehow we make it work, where will the Interest amount come from ?There will be more btc to be repaid then actual btc we have
Interest on a loan will come from profits made by utilizing the loan. This is no different than a loan denominated in dollars: when you pay the loan back, the interest you pay is not 'freshly minted money', it is just money that already existed in the system, but you are now the owner of.
In general: Use-cases for bitcoin are not dependant on how well the system mimics the lending properties of the traditional banking system, in fact bitcoin is likely useful because it has different properties than the traditional system. Bitcoin is a decentralized, permissionless, borderless, immutable and programmable system of value. What exactly the implications of this are is a story that is still unfolding, but it certainly does promise many exciting things. I think one of the most important is that it grants the user financial sovereignty, which is a rare and important thing in our increasingly Orwellian tech world.
i am asking on macro level, Say whole supply of 2.1 millions bitcoins are lent at 10%, from where does that 10% will come ? – KAKA BOOKIE – 2018-06-03T20:03:33.533
there will be increasing debt vs fixed supply – KAKA BOOKIE – 2018-06-03T20:11:10.563
In any system, not all loans will be (or perhaps can be) repaid. Indeed, in the legacy financial system, the derivatives and debt market is many, many times larger than the actual monetary supply. What you have described is a property of systems of debt, not an issue only inherent to bitcoin. In any case, if all of the system's liquidity is on loan, and then the loans are all called to be settled at the same time, then some loans will be unable to be repaid, and the debtor will lose out. Other loans will have made profit, and be able to settle fully. This is no different than the legacy system – chytrik – 2018-06-03T20:27:48.400
Put differently: A loan is always a risk, in that the loan maker may not be repaid later. A loan denominated in a deflationary aspect may present a larger risk, but it is the same type of risk, just amplified. This may change the willingness of someone to issue a loan, but it does not make the function of a loan obsolete. – chytrik – 2018-06-03T20:32:09.843
Do you agree to this : Due to Interest, bitcoins would be created out thin air by the banks/lenders, just like the current fait system which is said to be broken. And there will be defaults and market crashes etc..
So bitcoin is a good decentralised database, it has yet to find its usecase, in no way it can radically change the current system. – KAKA BOOKIE – 2018-06-03T20:47:24.203
Disagree: bitcoins cannot actually be created out of thin air: a bitcoin UTXO either exists, or not. A 'btc bank' may lend out more value than it actually holds (fractional reserve), but those loans would not be delivered in actual bitcoin (a valid UTXO). This is true even if the value of the loan is denominated in bitcoin, as it is impossible to lend the same bitcoin to more than one counterparty. – chytrik – 2018-06-03T22:03:20.430
If a btc bank made fractional reserve loans against it's btc holdings, then a default on loans would affect only that bank (and potentially it's customers). There is no option for a central authority to issue more btc in light of a crisis; that sort of existential systemic threat is not present in the bitcoin system. – chytrik – 2018-06-03T22:08:56.203
As it is now, a bank operating on fractional reserve orders in someone else's money to loan more than they hold. This aspect would not need to be any different for a Bitcoin bank. Ultimately, however, it is the government's that mint more money to increase supply but, in the case of Bitcoin, the BTC must actually exist and banks will not be able to offer more BTC than they can source. This is a good property of Bitcoin where it cannot be deflated by simply printing more. – Willtech – 2018-06-04T03:28:22.623
Okay we agree bitcoin banks will have fractional reserve and fractional reserve is equivalent to creating money out of thin air. They could give some bank credits as loans denominated and redeemable in bitcoins. As Govt will have no role this would make banks absolute powerfull. Who will maintain the repo rates? Further those bank credits wont be like reinventing fiat? bitcoin loans seems costly to me and if bitcoin has no capacity of lending then it cant replace fiat, if it cant replace fiat what its use ? – KAKA BOOKIE – 2018-06-04T13:18:39.063
You are approaching the question too narrowly, bitcoin's use case is not "it must replace lending or it is useless", I'm not sure why you see it that way. Is gold useless because fiat still exists? What about stocks or bonds? Or Paypal? Or the currency of a small country? Different financial instruments have different uses and purposes, some overlap in function yet peacefully coexist. Re: Lending: You've outlined a way that btc could be lent, now understand that regulation around how much a bank is allowed to lend could still be easily imposed, just as it is in the fiat system. – chytrik – 2018-06-04T18:59:07.933
