Link your bank and purchase crypto faster than ever before. In this release we fixed a crash on the Activity screen. The new update for the improved login speed with Touch ID is amazing. It is extremely fast now, while there used to be quite a delay before that was a tad bit annoying.
The new UI in the dashboard is awesome. I have a better understanding of each crypto and how it is shifting in the markets. I look forward to other airdrops in the future. This is my go to wallet app, and I plan to order a Blockchain secure ledger USB stick soon to keep my wallet with my offline as well. I have many other apps for storing crypto: Evercoin, Coinami, Coinbase, but this one takes the cake. I replied and nothing. Open and tickle and yet another ticket no response. Customer service is useless at best.

How disappointing this is. The other problem is that this company still uses the absolute slowest network. If your btc address starts with a 1 not only are you going to get slow transactions but slow everyone else down too. The new technology has been around for years now.
But the kicker is the horrible customer service. You guys need to fix the issue with sending from the trading wallet to your btc wallet immediately.

It has been nothing but lies since I started using this app. Within an hour they replied back with. I sent them screenshots of my deposit, and purchase of bitcoins with date, and time along with a screenshot of my bank showing them the bank released my money to them within 24 hours of the purchase.

As mining can provide a solid stream of revenue, people are very willing to run power-hungry machines to get a piece of it. Over the years this has caused the total energy consumption of the Bitcoin network to grow to epic proportions, as the price of the currency reached new highs. The entire Bitcoin network now consumes more energy than a number of countries. If Bitcoin was a country, it would rank as shown below.
The result is shown hereafter. Thinking about how to reduce CO2 emissions from a widespread Bitcoin implementation. Determining the exact carbon impact of the Bitcoin network has been a challenge for years. Not only does one need to know the power requirement of the Bitcoin network, but one also need to know where this power is coming from.
The location of miners is a key ingredient to know how dirty or how clean the power is that they are using. Initially the only information available to this end was the common belief that the majority of miners were located in China. Since we know the average emission factor of the Chinese grid around grams of carbon dioxide equivalent per kilowatt-hour , this can be used for a very rough approximation of the carbon intensity of the power used for Bitcoin mining.

This number can subsequently be applied to a power consumption estimate of the Bitcoin network to determine its carbon footprint. In this study, they identified facilities representing roughly half of the entire Bitcoin hash rate, with a total lower bound consumption of megawatts. Chinese mining facilities were responsible for about half of this, with a lower bound consumption of megawatts. The table below features a breakdown of the energy consumption of the mining facilities surveyed by Hileman and Rauchs.
This number is currently applied to determine the carbon footprint of the Bitcoin network based on the Bitcoin Energy Consumption Index. One can argue that specific locations in the listed countries may offer less carbon intense power. In Bitcoin company Coinshares suggested that the majority of Chinese mining facilities were located in Sichuan province, using cheap hydropower for mining Bitcoin. The main challenge here is that the production of hydropower or renewable energy in general is far from constant.
In Sichuan specifically the average power generation capacity during the wet season is three times that of the dry season. Because of these fluctuations in hydroelectricity generation, Bitcoin miners can only make use of cheap hydropower for a limited amount of time.

Using a similar approach, Cambridge in provided a more detailed insight into the localization of Bitcoin miners over time. Charting this data, and adding colors based on the carbon intensity of the respective power grids, we can reveal significant mining activity in highly polluting regions of the world during the Chinese dry season as shown below.
On an annual basis, the average contribution of renewable energy sources therefore remains low. It is important to realize that, while renewables are an intermittent source of energy, Bitcoin miners have a constant energy requirement. A Bitcoin ASIC miner will, once turned on, not be switched off until it either breaks down or becomes unable to mine Bitcoin at a profit.
Because of this, Bitcoin miners increase the baseload demand on a grid. In the latter case Bitcoin miners have historically ended up using fossil fuel based power which is generally a more steady source of energy. With climate change pushing the volatility of hydropower production in places like Sichuan, this is unlikely to get any better in the future.
What kind of work are miners performing?
To put the energy consumed by the Bitcoin network into perspective we can compare it to another payment system like VISA for example. According to VISA, the company consumed a total amount of , Gigajoules of energy from various sources globally for all its operations. We also know VISA processed With the help of these numbers, it is possible to compare both networks and show that Bitcoin is extremely more energy intensive per transaction than VISA.
The carbon footprint per VISA transaction is only 0. But even a comparison with the average non-cash transaction in the regular financial system still reveals that an average Bitcoin transaction requires several thousands of times more energy. More energy efficient algorithms, like proof-of-stake, have been in development over recent years. In proof-of-stake coin owners create blocks rather than miners, thus not requiring power hungry machines that produce as many hashes per second as possible. Because of this, the energy consumption of proof-of-stake is negligible compared to proof-of-work.
Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve environmental sustainability. The only downside is that there are many different versions of proof-of-stake, and none of these have fully proven themselves yet. Nevertheless the work on these algorithms offers good hope for the future. Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines and their exact power consumption.
