Question is really can you pay or receive a fraction of a satoshi?
i think therr can be no coin or altcoin which is small than 1 satoshi .
overall to send and receive 1 satoshi is full of loss . no profit . even transaction charge will be more times about lakh time of satoshi .
it means to send and receive 1satoshi will result in the loss of 1 lakh satoshi (in zebpay transaction)
That's right,satoshi is the smallest bitcoin/cryptocurrency denomination so far. Its value is 1/100000000 just like a cent is the smallest divisible unit when we talk of US Dollar. I do not think there is any likelihood of getting a smaller because even that one of satoshi is still extremely far behind the decimal.
I don't think it is not possible, satoshi is the smallest bitcoins.
