Why have dev`s made Circulating Supply so large for their coins?
Some are in the tens of billions & even trillions.
Why didn't they just follow Bitcoin at 21 million, or just limited to 100 million or so?
The reason i ask is the price movement over $1 on some of the coins with the larger supply will always be limited. On coinmarketcap there isnt any coin out there with a CS in the billions more than $2-5 max. The simple reason is the marketcap = price x CS. Your not going to get a bigger marketcap than BitCoin for now anyway.
For XRP for example to hit $100 it would have a MC bigger than the GDP of the US, of course thats not going to happen
I agree that each dev would have their own response, it is not a same answer thing, we can't possibly know it for every single one of them. I know a few, because they said bigger numbers attract people more in a marketing manner, having 10 million of something instead of 0.3 of something made them feel better, so they decided to do more, but that's just what I know, and a few examples, not really an exact science situation.
Others may have done for different reasons, like for transaction fees, or maybe bounty reasons, whatever else you can think of. So when you see something like that, you have to ask the devs or the team on why they did it and they will give you an answer about it, and most could be different from each other.
