What is The Purpose of "Decimals" in Every Tokens ?.
Enlighten me please.
You may have notice that supply of some tokens is in billions while for some it is around 1-2M. So to adjust fiat value, coin needs decimals.
For example, if ICO sale 100 tokens for 1 ETH each token worth $3.5 and people may send amount in proportions. But if ICO sale 100K tokens for 1 ETH, it doesn't require decimals as value of less than 1 token is negligible.
PS: suppose if Bitcoin wouldn't have decimals then you couldn't trade amound less than 1 BTC!
