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)
