There is no easy way in estimation of investments for coins (Cryptocurrencies), however we can use indirect predictors which might correlate to investments, most important such parameter is trading volume (Cumulative volume). As cryptocurrency markets are heavily influenced by manipulation ("Pump and Dump", etc), trading volume is not direct indicator of investments, but it definitely correlates to it.

Data used: Historical trading volumes were obtained from coinmarketcap.com, which operetaes from 2013 and is one of the most reliable data source available on web. Prices, Circulating supply and 24 Hour trading volume are updated from same website, for few currencies (Which do not have circulating coin numbers on coinmarketcap.com) circulating coin numbers are obtained daily from their block explorers. Page is updated daily at 00:15 (GMT+04).

Historical volume data was obtained on 7/Jan/2018, after that it is updated by daily volume (So if there is any adjustment in historical data it would not be visible here).

Coins below trendline are undervalued;

Coins above trendline are overvalued;

Coins on or near trendline are best following Trading Volume/per Coin - Price correlation.



Thing to consider before making any decisions based on this data:



Accuracy of data:

Check that price is correct;

Check that circulating coin number is correct;

Check that volume is correct (coinmarketcap covers full history).

Minor differences does not matter, but if difference is substantial, then better ignore prediction.



Circulating coin supply.

For Cryptocurrencies that are several years old many coins are lost and there is no reliable method to correctly identify this, coin loss is probably function of time. So Circulating Supply for older coins will be somewhat incorrect, therefore real trading volume per coin will be higher, current model does not take this into account.



Some coins are traded on one site, others on several and therefore might follow different trendlines. coins on many/larger exchanges may not behave in a similar way as coins with a smaller investor reach, current model does not take this into account.



Coins on trendline or near it are most stable and best for long term investment, their growth is highly probable and will be correlated with increase of trading volumes.

Chart may contain "dead coins".



Warning: Cryptocurrencies and investments in them is a high-risk activity, You may loose your investments. Also consider many cases of fraud & hacking. Do not invest more than you can afford to loose.
