FAQ:

What is Crypto25?

Crypto25 is an index, that tracks performance of the 25 altcoins with the highest market cap compared to bitcoin. So the index will go up, if the 25 altcoins will perform better than Bitcoins and will go down, if they perform worse.

Why do we need such an index?

Indices are very popular in the world of finance and it is sad to see, that there is no such project in the altcoin world. There are several advantages that come with indices: You can check one chart to see how most of the altcoin market is doing. Also having an index makes it very easy to create products that track the performance, for example an ETF, Futures or options. Another cool thing is, that you can check of your portfolio outperformed the index in the mid to longterm!

Who decides what the index weights are?

Coinselection:
Optimally the top 25 ranked coins on http://coinmarketcap.com/ are used for the index, but coins that fail to be liquid enough, will be dropped from the index. This is done to ensure, that one can always invest according to the index and not run into liquidity problems.

Index weights:

Index weights are calculated using their relative marketcapitalisations with the following constraints applied:

• No altcoin weight can be >10%
• Index Rank 1-5: >=6%
• Index Rank 6-10: >=4%
• Index Rank 11-15: >=2%
• Index Rank 16-20: >=1.5%
• Index Rank 20-25: >=1%

The weights are then calculated using excels solver using the above-mentioned constraints.

How can I invest to get the same performance as the index?

You will have to invest into the same coins as the index weights and update your portfolio once a week, when the index weights change. In a few weeks, we will launch an ETF, that will do those investments for you.

Feel free to ask anything you like!

Wow that looks pretty cool. Is it just the top 25 coins on Coinmarketcap?

No, there are strict rules, that are followed to calculate the exact weights and coinselection. I updated the FAQ in the op.

This weeks weights were calculated in the following way:

The following currencies were excluded to the above-mentioned liquidity problem:
- FuelCoin (FC2)
- Mastercoin (MSC)
- Quark (QRK)
- Zetacoin (ZET)

I can't open the site, error is "server not found".

Could you please check, thanks.

Edit: Now it works, thank you!  :)

Cool stuff...like our very own FTSE or S&P index.

Cool project!

Thanks!

Yes, that is how it is intended. It will be interesting to see how this project develops.

Also I am very curious, how the top 25 cryptos will perform relatively to the BTC. What do you guys think?

It will be a mostly flat line in 2015, but 2016 should see quite a bit of upside action, so get ready to get bored for a while )

Interesting ;)

You can add your voice here: https://bitcointalk.org/index.php?topic=860533.0

I have to agree mostly flat because most (except for a small %) require BTC for the alt coin purchase.

Yes, but there were serious BTC inflow to cryptos in 2nd half of 2013 followed by a big outflow since. So if we think that longterm BTC will increase in price, it is not too unlikely that there will be a net-BTC-inflow to cryptos.

The index outperformed Bitcoin a total of 4%.

It really is! Watching this...

Thank you!

Lets see if it can beat 20% soon.

Index was successfully updated.

Also starting from next Week, I will also post the real portfolio gains corresponding to the underlying assets, because I started the ETF.

How do I buy into the etf?

Interesting, watching.

Please let me know if I understand this correctly:

The coin with the  highest "24hr effect on index  (weighed)" =  is  it the best performing?

But would that be in the last 15 minutes - since the chart is updated every 15 minutes?

Not really, It just means that the INDEXWEIGHT*COINPERFORMANCEOVER24HOURS is the highest. So a coin with 1% that moves 5% will have 0.05% influence. If a 10% coin moves 10% it will influence the index 1%.

This new stat is always comparing prices now to the prices exactly 24 hours ago.

Really interesting and useful project can't believe this hasn't been done before.

Following closely.

Pretty unexpected result.

Looks like very constant outperformance. Lets see when this stops!

Not very transparent if I understand this correctly. They don't publish any rules.

Would be interested in seeing and updated index   ;D
