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.
There are transaction fees in NEO but it less compared to the ethereum blockchain. But i'm not sure about when sharding and raiden will be implemented and then it looks like it can reduce the transaction fees of ethereum.
I can assume NEO is the only best candidate for you compared with another existing platform. Lisk looks good but it's not a smartcontract platform and not so popular as NEO.
