Away from the rampant speculation of the markets, bitcoin is making life easier for many. Last year, Nigeria ranked third — behind the U. Like many citizens in developing countries, Nigerians use bitcoin for remittance — sending funds to family members. Increasingly, crypto-based remittances are favored due to low fees and fast confirmation times.

Cryptocurrencies like bitcoin enable users to seamlessly transfer value, wherever they are in the world. And there are benefits over and above helping people in low paid jobs keep more of their earnings, like the ability to circumvent geopolitical conflicts or evade capital controls.

Speaking of Venezuela, its notorious hyperinflation is but one driver of bitcoin use in the region.

For many, bitcoin is not just censorship-proof but corruption-proof. And unlike fiat currency, it cannot readily be seized — a feature especially appealing to those living under a dictatorship.

Simon Chamorro, a Venezuelan-born entrepreneur, co-founded Valiu, a Colombian startup that is focused on crypto remittances for Venezuelans. Seven million people have left the country since the protests against the Maduro government started, creating a massive diaspora, many of whom are in Colombia, and almost all of whom send money home to family members trapped in the country. With central bankers now warning of rising inflation in the West, all the more reason seek protection from any reduction in value of Purchasing Power Parity PPP on foreign exchanges.

The bottom line is this: as renewable energies become cheaper, bitcoin will become greener — and so will everything else.

There is no question that bitcoin, the blockchain, cryptographic currencies, and DLT protocols must all seek to lower their energy consumption and reduce their carbon footprints - but we all do: central banks, financial institutions, the mining sector Those fiercely opposed to the cryptocurrency will continue to highlight its environmental impact without putting the case in context.

Defenders, meanwhile, will go to bat for bitcoin like their lives depended on it. If you are interested in engaging in the debate in the global community of digitalists and policy makers, I suggest you use reliable facts to make your case. It is perfectly acceptable to come down on either side of the debate but make an informed case. Spouting rhetoric from the last thing you read in social media or the gutter press, or from the last talking head your listened to in media land, is not submissible evidence in this global forum, and makes you look like a Luddite.

I cover fintech, digital assets, and sustainable investments and promote policies for a transparent, secure and quality digital financial future for everyone. The academic efforts that get breathlessly reported in the press tend to assume either an energy mix which is invariant at the global or country level. As discussed, Bitcoin seeks out otherwise-curtailed energy, like hydropower in Sichuan, which is relatively green.

Any reliable estimate must take this into account. The prospects look even sunnier when you consider the changing nature of Bitcoin security spend.

Why does Bitcoin need energy at all?

This is because most of those coins were issued at cheaper price points. If Bitcoin ends up being worth substantially more in the future than it is worth today say, by an order of magnitude , then the world will actually have received a discount on its issuance. The energy-externality of pulling those Bitcoins out of the mathematical ether will actually have been very low, due to the historical contingency of when, price-wise, those Bitcoins were actually mined.

Coins only need to be issued once. As any Bitcoin observer knows, issuance as a driver of miner revenue will decline with time. Fees will necessarily grow to account for a much larger fraction of miner income. Fees have a natural ceiling to them, as transactors must actively pay them on a per-transaction basis. If they become too onerous, users will look elsewhere, or economize on fees with other layers that periodically settle to the base chain.

This is not under debate.

This question relies on a kind of utilitarian logic about which industries should be entitled to consume energy. In practice, no one actually reasons like this. The Bitcoin-energy supplicants are mum when it comes to the energy used to illuminate Christmas lights, to power the data centers behind Netflix or to distribute untold millions of single-serve meal kits. Something duly purchased cannot, by definition, be a waste. Fundamentally, millions of individuals the world over still value physical, bank-independent savings, so it still gets pulled out of the ground with regularity. As long as people value Bitcoin, so, too, will the block-space auction continue in perpetuity.

The Bitcoin-energy worriers need not despair, however. But the way bitcoin mining has been set up by its creator or creators — no one really knows for sure who created it is that there is a finite number of bitcoins that can be mined: 21m. The more bitcoin that is mined, the harder the algorithms that must be solved to get a bitcoin become. Now that over Instead, mining now requires special computer equipment that can handle the intense processing power needed to get bitcoin today. And, of course, these special computers need a lot of electricity to run. Proponents of bitcoin say that mining is increasingly being done with electricity from renewable sources as that type of energy becomes cheaper, and the energy used is far lower than that of other, more wasteful, uses of power.

The energy wasted by plugged-in but inactive home devices in the US alone could power bitcoin mining for 1. But environmentalists say that mining is still a cause for concern particularly because miners will go wherever electricity is cheapest and that may mean places that use coal.
