I like EFL as a trading coin because of the low supply. As soon as you add merchants the price will be pushed down as people buy. Guldencoin is a good example of why merchants and services is a bad idea for price gains but it's great as a currency.
About the low supply : You are missing the point, literally here

. There is no such thing as low supply with cryptocurrencies. You are tricked by the decimal point. You can put the decimal point anywhere at your convenience. Even a satoshi is not a hard limit. There is no fundamental difference between NLG and EFL with respect to supply, because they are "infinitely" devisable. NLG just has the decimal point about two positions to the right. To make you feel richer ? What a joke

. Now they think the price goes down because there are too many of them (being mined/inflation). That reasoning is so fundamentally wrong that I am astounded by their (who are they ?) stupidity. When you want to compare things you will first have to normalize. Compare NLG with Bitcoin for example :
- There will be 80 times as many NLG as Bitcoin (or EFL) ever (if they keep their hands of their settings)
- NLG is being mined at a rate of 225 per minute (after some manipulation Bitwise mentioned before), Bitcoin at a rate of 2.5 per minute and EFL at a rate of 6.25 per minute
If you normalize the NLG amount with Bitcoin you would get 2.8 NLG per minute which means that the rate of inflation is currently about the same as with bitcoin and less than half of the EFL inflation rate. If you would only look at "available supply" the picture only changes slightly (there are currently 20 times as many NLG as Bitcoin/EFL)
And now they are trying to trick the market again by forging their fundamentals by a factor 10

If you don't understand the above you will not be able to understand marketbehaviour when they change inflation rate arbitrary again. If you arbitrate, people need to trust the arbitrator. That is the exact opposite of what cryptocurrencies are intended for.
About being great as a currency : Any cryptocoin is potentially great as a currency, although a larger marketcap and a predictable value is greater. Cryptomoney is great because it is rare, portable, recognizable, durable and devisable.
