IS IT TRUE TETHER USD (USDT )IS REASON FOR MARKET CRASH?

Hi daer steemian
Let me share with you something on market manipulation of cryptocurrency.This time am going to explain how tether can manipulate this market.
Tether usd.this is cryptocurrency which has value equal to paper dollar.but this coin issued by bitfinex management
Alot of cryptocurrency traders normally they use this coin to preserve their other cryptocurrency value, and this occur when other market of cryptos going deep.

Many people get out of cryptocurtency market by printing their crypto value into paper money.due to this usdt , it canna be a major way of crashing cryptocurtency.
But in other hand this is huge method or technique used by most succefully trader ,ussually they timing market by putting money in tether for timing market to go up.
