In recent blockchain based project iost making huge promise team is always active I have seen best marketing as well as active team after trx. I think it will be compitetion for trx, eos mainnet launch . What do you think about this guys
That's a marketing word. you should not try to believe it. The team is using it to create a FOMO to the investors and traders. It will be similar as trx or even eos, the launched of the mainnet doesn't give a lot of impact to the coin itself. In fact that developer just try to create fear of missing for anyone.
