Also I would to mention a big update from Ethereum side. Vitalik was talking about network emprovements that will allow to speed up the network to around 1000 tx/s. 2019 will bring nice updates.
Nice. Without a doubt, Ethereum will scale until it becomes flexible enough for people in the mainstream world. Increasing TPS is key towards the adoption of Ethereum and its tokens among individuals, businesses and corporations alike. The upcoming Casper PoS and Sharding upgrades, will totally rock Ethereum as they drastically change the smart contract platform for the better. Right now, Ethereum might be slow and costly in fees, but everything is bound to change sooner or later.
Once it scales, then it could be compared to other cryptocurrencies which are fast enough for the mainstream world. On the other hand, Tron is a smart contract platform which could greatly rival Ethereum since it's much faster, cheaper, and it's fully compatible with the EVM. This means that existing developers within Ethereum, could migrate their projects easily within the Tron network, without having to learn a new programming language at all.
Therefore, the future lies in not only fast and cheap cryptocurrencies for daily transactions, but also for smart contract platforms that are highly scalable for the mainstream world. In my opinion, the fastest cryptocurrencies right now are: Bitshares, Tron, EOS, Ark, Lisk, Stellar, Ripple, Nano, IOTA, NEO, and even Credits.
