One of the blockchanis which cheapest fees is NEM.
A simple transfer transaction up to 10000 XEM costs only 0.05 xem
which at current prices would be about 0,01 USD.
The transaction costs increases as the amount of transferred XEM is bigger
but is capped at max 1.25 XEM per transaction.
The fee can vary depending of the type of the transaction
like if a simple or encrypted message is sent within transaction
or an importance transfer transaction is sent or if a multisignature tranasaction is sent.

So true. I've been using NEM for a long time, and I'd have to say that it's one of the cheapest cryptocurrencies out there for micropayments. On top of that, transactions settle almost instantly on the Blockchain. Yet, NEM is undervalued sitting below the $1 range as other cryptocurrencies gain traction. The NEM blockchain can also be used for smart contracts via the use of an API. Unlike Ethereum and other leading smart contract platforms, smart contract operations are performed completely off the NEM blockchain. This reduces the burden on the network, providing low fees and fast transaction speeds for everyone. While it's still under the radar of most investors and traders in the crypto market, I believe that the time for NEM will come as fees rise within popular blockchain networks like Bitcoin and Ethereum.
Nonetheless, I'm surprised to see many coins out there with ridiculously low fees. This makes crypto extremely practical for micropayments and cross-border transfers. It's even better than traditional credit/debit cards, as well as, money orders. The world is yet to adopt crypto/Blockchain tech to a full extent, in order to rival traditional payment processors powered by Fiat. As long as we have cryptocurrencies with blazing-fast transaction speeds and low fees, there should be nothing to worry about. Just my thoughts
