If BTC's price is manipulated anywhere, the market adjusts for it everywhere.
Eth is $400 on Coinbase, Bitcoin is $12000 on Coinbase
Print 1,000,000 Tether
Buy $1,000,000 of Eth on an exchange that supports Tether
Sell $1,000,000 of Eth on Coinbase
Buy $900,000 (arbitrary post-sale amount from selling Eth) of Bitcoin on Coinbase
Another scenario:
Bitcoin is $12000 on Coinbase
Bitcoin is $12000 on another exchange that supports Tether
Print 1,000,000 Tether
Buy $1,000,000 of Bitcoin on the exchange that supports Tether
Bitcoin is now $12050 on another exchange
Coinbase price of BTC rises as arbitrage bots and manual traders purchase cheaper Bitcoin on Coinbase and sell it for profit on the other exchange until prices equalize
I don't know how to explain it any more clearly to you.
>plus only bitfinance would be able to print/create tether
Yes, but whoever controls the printing could then use the Tethers on any exchange that supports them.
>also, there's no evidence that companies what you claim they could do
You asked for an explanation of how it could be done, not evidence.
Sure, I didn't ask for evidence. Now, I am. Where's your evidence?
Why not?
>Sure, I didn't ask for evidence. Now, I am. Where's your evidence?
You need to specify what exactly you want evidence for. Then you need to google it, because that's what I'm going to do, assuming you want evidence of something like arbitrage.
