All of those analysis and predictions don't have any guarantee, they're only giving what they think will happen if you're going to also believe on them, that's on you. If the price will fall down, that's because it's expected that this year we'll have a heavy decrease due to being bearish of the market.
but if ethereum can fall to $1200, that mean USDT will be above ethereum in marketcap but which may not last longer until later.
Expect that any highly volatile asset that drop a lot in few minutes and can be replaced based on its market cap and so, that's possible but it's not a big deal IMHO.
