After the recent refill of Bitfinex wallets with 90 mln USDT coins from the Treasury, the coins have been sent back from the exchange. They served their purpose of supporting the Bitcoin quotes and then the Treasury reclaimed them.
Earlier this week 35 mln tokens were returned and on Tuesday Bitfinex sent back another 40 mln USDT coins.
Currently, the Treasury contains over 205 mln coins. Some analysts believe that Tether has played its significant part in the recent market recovery.
