I heard that the team decided to suspend bridge.

Is it a technical issue with bridge? Otherwise, it is not a good idea to suspend it because it will harm waves further.

What are other directions? Is it possible to state the resumption date in announcement? Also, why can't you replenish liquidity once depleted?

You can try to use BUSD, DAI, ETH, LTC, WAVES etc. or wait till liquidity is refilled again. A lack of liquidity for the USDT/USDC gateways is more common due to the greater popularity of these gateways among users. Unfortunately, we do not have eta opening these gateways again. Please be aware that we do our best to speed up the process of refilling liquidity for the gateways from hot wallets. As soon as liquidity is refilled the transactions which were not processed earlier go through. Then if there is enough liquidity, the withdrawals are opened.
