I read an article like a few months ago where TRON was said to be free to use (i.e. that there are no fees). If that's actually the case, then their USDT tokens can be transferred natively without having TRON in your wallet.
Can anyone clarify this? Where or how can we test using Tether on the Tron blockchain, and is it true you can use it without paying fees? That would prone to blockchain spam, i'd rather fees be paid with USDT itself...
As far as i know, you need satoshis to use it on the Bitcoin blockchain, and gas on the Ethereum blockchain. Why would Tron let it move for free?
