XMR has 12 decimal places
We need more.. since people need really to do new coins with Billion of coin cap or even Trillion.
You can see that these have a big problem to trade at 0,00000001 statoshi
What? Are you aware of how it's implemented?
The variable set to regulate that has a range of 0 to 18,446,744,073,709,551,615 bits available when unsigned.
So, if 8 decimal places were taken in XMR, the number of coins would be 184 billion ..
These aren't numbers that are just picked to impress people LOL .. it's a number set to maximize the variable range efficiently
Do you even read the source?

Can u plz tell me in short, what is the highest no. of decimal places that any altcoin allow ?
