Tether has been used to artificially inflate the crypto market as a whole but especially BTC and ETH. In my opinion we will see around a 75% price collapse for BTC and 60% for ETH. Regulations will come later this year that hurt high energy use tokens like BTC and ETH (until they fully roll out Ethereum 2.0) This combination is what pushes them to these levels. In the end the XRPL and the Flare network save BTC from total destruction through their ability to process BTC transactions on their network reducing the energy consumption and allowing it to fit within the new "green" regulations that are coming.
