A few new changes with USDT. Now you can transfer in Tether (USDT) from Ethereum (ERC-20) or Tron (TRC-20) networks. Just make sure you copy the right address for the network you are using as they are different. Now there is a drop down menu to select the network you want to use as seen below. The mining/dividend payouts has also changed. Now mining with USDT will accumulate BFG(BTC) tokens and BFG(BTC) tokens are paying out a higher rate of USDT. This may be temporary however as it hasn't been fully reflected in the monthly estimates.
The advantages here are that you can buy USDT on Tron network and transfer it in for cheap, and when you mine with it you now receive BFG(BTC) which most people probably think are more useful at the moment. I guess this is all pretty trivial though as the merging of the two tokens should take place fairly soon and then only BFG(BTC) will exist. This move seems a bit irrelevant but eventually ETH gas prices should come down (with ETH 2.0) and by allowing Ethereum users that maybe don't know what Tron is to transfer in USDT will allow for a wider customer base for BetFury in the long term.
