This might be a dumb question but I cannot find an answer and I'm really curious about it. So there are many test networks like Rinkeby, Kovan, Ropsten etc ... These testnets offer free tokens (Faucet), but many of them offer some small amounts that are not enough for a lot of testing. I have many questions ...
Where does this "faucet" come from ? Is it unlimited ? If not, why not ... ? If it is only for testing and has no value, why are we limited to get only specific (sometimes very small) amounts of test token ? Can anyone create a testnet with free tokens ?
I have a lot of questions but I will limit myself to these ones for now.
