I want to transfer USDT from one address to another. ERC20 detucts a lot of fee but TRC 20 on tron network, the transaction is free of cost.
I want to know if TRC 20 blockchain is safe to use and we can store our USDT there for long term ?

yes, it is safe to transfer USDT via TRC 20 blockchain as there is no fee involved in the transfer so it works out cheaper than using ERC20. I can say it's safe - I've done it many times before. You just need to ensure that the receiving address accepts TRC20.
I'm not sure what you mean by storing USDT on TRC20 for long term, I'm afraid for me at least you'll need to elaborate a little more so I can understand what it is you're asking.
