Too Long; Didn't Read
Tether (USDT-ETH) now accounts for between 25% to 50% of the network’s usage. The network has been hovering at, or near, capacity for some time. There are now calls for an increase in the “gas limit” – which will effectively increase the block size. Not all Tether's fault – a decentralized gambling platform called FairWin is also gobbling up huge amounts of capacity. A lot of the gas issues will be fixed in the upcoming Istanbul upgrade which will hopefully start solving the major scaling issues.
