What you say is probably right. But see many talk about it now days. Hope it will be possibly to buy crypto at Binance with fiat soon. Than Coinbase will be history. The fees at Coinbase are crazy
Those people who are saying that coinbase will list TRX are just probably trying to spread FOMO in order to boost it's price. I also hope that another good exchange will help us buy crypto with fiat soon, I am starting to get tired with coinbase's shits when buying crypto with fiat. For now, just try to ignore those who spread the FOMO for TRX. Let them do as they please and don't believe them.
