Bitcoin and Tether are different types of cryptocurrency.bitcoin is a peer-to-peer digital currency governor by any financial institution. Tether is a stable coin, it have same value of the us dollar. That's why it is less volatile than Bitcoin, it can also be use for trading on exchanges or it can be stored value. Both have their potential of Bitcoin and Blockchain technology are endless. It's a stable coin backed by us dollar, Both have their unique advantage. How well do you trust Tether stable coin?
Okay, I've gone through all you've got to say and I don't get the
versus idea about the title of the OP.
Are you bringing them both into context of trust/reliability or into context as per value? I feel you really should have adequate your point clear on this.
Something I'll also like to point out though,
Bitcoin isn't govern by any financial institution as that would have made the coin a centralized coin but, it is in itself the only convinced decentralized cryptocurrency out there
.
Again, Bitcoin is a p2p cryptocurrency and so is the Tether (USDT).
Another thing to note is, being dollar pegged doesn't make Tether any better coin than we have in Bitcoin. All existing altcoins are rooted with Bitcoin.
