ALT coin Indexes, like Dow Jones or SP500, but for crypto coins

[alt19]

This thread is to promote indices for altcoins (like Dow Jones and SP500 for traditional stock market)

Why using indices:
1) easy to estimate market trends on the whole
2) stability
3) say 'no' to more and more new coins which are destroying altcoins market idea. Using Indexes means dealing only with fixed number of coins included.

There are ALT19 index (19 cryptocoins included, values are in BTC) and ALT100 index (100 cryptocoins included, values are in USD).

If you know any other altcoin market indexes, post it here, please.

great initiative!

I've been looking at ways to promote a core group of cryptos as 'bluechip', something to separate them from the packs of zillions, though I don't think like regular markets it be based purely on market cap, need certain standards also to separate the scams.

ALT19 Index calculating
7 constant coins included:
Litecoin - 20%
Namecoin - 12%
Novacoin - 7%
Terracoin - 7 %
Peercoin - 7 %
Feathercoin - 7 %
Primecoin - 7 %
+ 12 variable coins (Worldcoin, Quark, Doge, Digital... a composition is changeable but it's weighted to match previous index values when there is any change)
Calculating is in BTC. First value is 100.

Care to share why % are fixed?

This index is being calculated since 2013 so when it started it was based on coins that were traded with large volumes on BTC-e and Cryptsy.
But price absolute values are extremely different so you need some coefficients.
Besides some coins are more important (Litecoin, Namecoin...) so more weight in % they have.
If traded on BTC-e and also on Cryptsy - more weight.
And % were fixed at the beginning. It was necessary to calculate ratios. That's about ALT19 index.
And there is also ALT100 index where 100 coins included with 1% weight each.

Ok, coefficient is clear but why is it fixed if You claim that initial basing is on large volume? What if volume changes? How will You adjust for %?

I've thought of this too over the past few months, but the weights should not be fixed. Let me see if I can come up with something exact. I have a formula in my head.

The general idea of indexes: to compare, to see trend history relative to the value at the beginning.
If we include new and new coins or change weights every time, there will be no stability. You see how new coins are dumping altcoin market now.
Using Indexes means dealing only with fixed number of coins included.
About % weight: there may be some corrections in future if things change.

Well since you cannot buy these indexes (you don't have to, because there are no fees), I do not see any reason behind this effort. But thank you anyway.

[alt19]

Things changed since December and there are some changes in ALT19 and ALT100 Index calculation made also to match your ideas, suggestions.
It became more transparent and usable.
Now you can view not only the charts http://www.alt19.com
but also all the components: alt19.com/marketindexes.html
Thanks to everyone for your support!

Several months ago I've added some new altcoin market indexes.
Some results are quite unexpected.
I mean how prices changed since it was first calculated.
The worst is ALT_INNOVATIVE index (the components of the index are coins with innovative features).
It dropped to 10.744 (the first value was 25 at the end of June 2014).

[alt19]

for comparison, ALT_Collectibles dropped to 18.29 only.

[alt19]

ALT_WORLD (coins with geographic associations, like Spaincoin, Auroracoin, AMC...) now is 13.94

[alt19]

ALT_ANIMALS, ALT_JEWELS, ALT_BTCE now are around 25, like they were before.
All these new indexes are with a base value of 25, first calculated in June 2014.

So the worst are ALT_WORLD (nothing strange) and ALT_INNOVATIVE (that is quite unexpected).

[alt19]

Altcoin Indices Today:

ALT_GALAXY      30.569   
ALT_JEWELS      19.983      
ALT_ANIMALS      13.818      
ALT_INNOVATIVE      10.180

Coins with galaxy and gem theme succeeded last year.

Note: Marscoin (+697% today on Poloniex) is not included in ALT_GALAXY index.

This is a good idea.  Minus the crapcoins though.

This can be difficult to implement.
Many of the altcoins are just shit and it will take a huge market cap and a pump to get an altcoin into top 100.

Not all coins are for wide adoption and payments.
Some of them are just collectables, but it's not bad.

ALT indices (ALT100 particularly) help to trade Litecoin, it shows altcoin market trend.

Top 100 market cap coins are not a good base for Altcoin index, in my opinion, in this case index base will vary too often and will affect trend history relative to the value at the beginning.
