By The Way, I don't understand the words Shilling and Shiller,
Any one who please tell the term shilling?
In crypto, when someone promotes his or her own portfolio (the coin s/he owns) with the intention of selling it at a good profit, that is usually referred to as shilling. A shiller is someone who do shilling. Others may have a slighlty different description.
But if you compare this term "shill"with the dictionary meaning, they are different in meaning.
According to Wikipedia:
The shilling is a unit of currency formerly used in Austria, the United Kingdom, Australia, New Zealand, United States and other British Commonwealth countries. The shilling (1/-) was a coin worth one twentieth of a pound sterling, or twelve pence.
I think shilling of a coin is simply means listing a coin/ token from the last decimal place, that is, from $0.00000001 ( 8 gwei) for trading.
