As at ethereum mentioned, token ERC20 can be used as Loyalty points. So consider a Forex website which wants to send 1 of its token to each clients who have traded 1 lot or so. In other words its smart contract event has coded to sending token per each trade or even for each sign up in its website. my question is if the transaction fees apply to all sending token as loyalty points to the website's clients, it will be horrible and gainless. I am starting to learn solidity , so maybe I'm in a wrong way. please help me know there is the transaction fees? and if it is what is the minimum amount?
Every change to the blockchain happens as part of a transaction, and every transaction has a transaction fee associated with it.
Giving someone a token, then, requires paying a transaction fee. Fees vary depending on demand and how quickly you need the transaction to be processed. In recent history, fees have ranged from a few cents to a couple dollars.
