I am looking at setting up a project - something small - it will require small micro payments of less than $2-3. So high volume (hopefully) but very small amounts.

I looked at ethereum but the transaction fees and processing time would not make it viable. I have looked at NEO and it does seem to have potential as I am correct there are no transation fees?

But I assume if there are no fees processing times are slower than if you wanted to optionally pay a fee?

I looked into IOTA but after reading  $hitcoin dot com I was put off.
