It has been answered so many times why so many coins. To make an average phone miner mine like 2 coins a day not 0.00005 a day. Much prettier for the average user. Read pages before, it has been analyzed better than how I do it.
This project AIMS everyday users also, not only "crypto-people".
This is a great point. From an investor standpoint, it doesnt really matter how many coins their are. This point was most obvious when back in 2013-14 when a coin named "42" came out. There were only 42 coins. So obviously most people didnt even have 1 coin.
But to investors, it is the % of the marketcap you are getting, and the price you paid for it, and the price you sell it for.
In reverse, it there were 20%, or even 5% of the total coins in circulation that were being plucked off the top for the dev team, then investors would worry about "all those coins" the dev team may "dump" and crash the market.
In this case, the dev team is getting ZERO, and they are buying in like everyone else.
This case, all investors like to see, because that means the devs believe that they will be successful, and are putting their money up like everyone else.
The devs tried to think about what amount would "look the best" for a regualr user, the person who is mining on their mobile phone.
Do we want them to see .00034 coins in their wallet, or would 34 coins look better?
Then they actually ran an experiment, with a test group of subjects to see their reaction to different things.
One of the biggest things that people in the test group cared about was how many coins they had.
Like I said % of coins matters to us as investors, not coin totals. We want to know how much it costs, what stake my investment will get me in the coin, and what the price projections in the future are if every goes according to the plan, and what it can sell for at a later time.
If we like the devs and the plan we buy, if not we dont we pass.
In the case of the end user of Electroneum, the person mobile mining, billions makes sense because the end user will get full coins.
