August 26, 2019 Ethereum’s share of Tether volume rises to 40%, highlighting transaction scalability issues.

Originally issued as a token solely on Bitcoin’s Omni platform, the ERC-20 version of Tether has gained significant traction in 2019. Transactions in the ERC-20 version are currently the largest source of Ethereum transaction fees, and overall network utilization is roughly 90%. Vitalik Buterin emphasizes sharding and Proof of Stake approaches in Ethereum 2.0 as critical to long-term scalability, necessary for low-fee access for both Tether and other applications.
