Hello,
for planned development of BitcoinCalc.com we are looking for inspiration, ideas or feature requests. There are many calculators or statistics sites around, but is there anything that you are still looking for and badly need? What would you expect to find on the domain? What features, calculators or statistics are you missing in bitcoin eco system? What we should bring on the domain?
We will reward best and most helpful ideas by few Bitcoins.
Thank you!

If you are providing exchange rates, then there are concerns.

Quite often the rate at Mt. Gox is taken as the "official" rate.

However, is that the last trade, the current best bid, or the current best ask?

Additionally, that rate doesn't consider slippage.  Perhaps just a few BTC are available at that level, and to buy even less than 50 BTC sometimes causes a half-percent swing.   So maybe there needs to be a quotation for a specific action (buy or sell) and for a specific depth (slippage taken into account).

Also, should Mt. Gox be taken as the "official" price.   Perhaps it should be a weighting where anything that is an outlier gets discounted or omitted.

This is something that is beginning to become more important as a reliable source for "current price" is needed and is pretty much inconsistently determined at this point.



Also, there are two ways to compute exchange rates for currencies other than USD.  For instance, there are BTC/AUD markets but that may be far from what a merchant really wants, the BTC/USD converted to BTC/AUD using the "official" AUD/USD exchange rate.   The merchant may not plan on converting to AUDs, but just needs to know what price to charge.  So using the latest BTC/AUD may reflect a price unfavorable to either the merchant or to the customer at any one point in time.


There is no accurate history of trading volume per-day that includes all exchanges.  BitcoinCharts gives each specific market, e.g., Mt. Gox's BTC/USD,  BitSTAMP's BTC/USD,  BTCChina's BTC/CNY   but there's no total for the day of ALL the exchanges combined.      As bulk and direct selling becomes more widely used, this total may not mean as much though. so maybe this isn't as important as it once seemed.

The current "currency inflation rate"  ... e.g.,    in the past 24 hours, how many coins were issued, then compute that daily inflation rate on an annual basis.  e..g, at this moment, Bitcoin Watch shows 131 blocks produced in the past 24 hours.  That is 6,550 BTC.   So 6,550 against 10,027,100 that exist at this moment = 0.00065323  daily inflation rate, X 365 days/year = 0.238428858,  so the currency inflation today is at 23.8% on an annual basis.  This will bounce around depending on the number of blocks occurring each day but this is a metric not reported much elsewhere.

Hello, thank you those are great ideas!

I was thinking about slippage. But partly clarkmoody offers this.

Also on the mining side I haven't found any comparation of different alt chains to bitcoin so you can choose everyday what to mine. This will be important as difficulty of BTC will rise with specialized hw and those with standard hw will seek for fastest break-even.

Someone once posted a calculator which would allow you to post the price and rate that you are making a purchase or sale of Bitcoin and it would give you the price at which you would need to sell or buy to at least break even.

That is sorta handy.

First seastead company actually selling seasteads: Ocean Builders https://ocean.builders  Of course we accept bitcoin.

Hi, I quite don't understand... do you mean break-even when mining?

I'm proposing bitcoin calculator index that would be indicating whether to mine bitcoins or other chain and when to stop (when profit drops below zero)... I'm not aware that there exists something like that... Some miner profitability index with past graph statistics...
