Ethereum has 1,000+ dapps with over $2.6 Billion transaction volume in 2018, but only around 20,000,000 transactions in total. Compares to EOS (over 100 M) and TRON (over 98 M) only in less than 6 month. These 2 blockchains are stealing developers from Ethereum because it is slow and costly. I think sidechain solutions like POA will be very helpful. 2019 will be the year for POA.
