With good luck, I encountered another opportunity to move bricks. There are still opportunities in the chain.

Well, look at the picture, I finally bought 30 etc with 622u (average 20.733u). The current price on Binance Exchange is 21.62u, with a profit of approximately 26.61u.

Cross-chain bridge fees will be deducted later.

Deposit to Binance first, about 70 blocks are confirmed (each block takes 15 seconds), which takes about 17.5 minutes.

Choose eth-usdt for withdrawal, the handling fee is 4.5u, and the profit becomes 22.11u

Next, use a multi-chain bridge to cross-chain eth-usdt to etc-usdt.

Cross-chaining here used to be free. You only need to support the eth handling fee, which is about 1.5u, and the profit becomes 20.61u.

In this way, a brick move is completed, multiple chains are determined in about 15 minutes, and USDT reaches the ETC chain.

The final profit was 20.61u, which was still very easy.
