NO FEES!!!
IOTA enables companies to explore new business-2-business models by making every technological resource a potential service to be traded on an open market in real time, with no fees. This isn't the first cryptocurrency to attempt this but IOTA is approaching the concept of transactions without fees in a different way and may I add a smarter way.
How different you ask? They have completely changed, or should I say removed, their blockchain structure to a scalable, lightweight distributing ledger. This distributing ledger is able to withstand the long term effects that come from a fee-less currency, which was the main thing the other currencies that attempted fee-less transactions were lacking. They call this ledger the Tangle...
Not only do large transactions not have fees, micro transactions do not either! This is almost unheard of even from former fee-less currencies.
