Tether is really a problem, it has been discussed a long time ago about whether or not $ 1 / 1USDT support. In addition, Tether was accused of being behind a pump of bitcoin prices in 2017. For those reasons, Tether was not always trusted by users.
Although there are many accusations but Tether is still in top 10 CMC , I don't understand why it could be so? I do not accuse Tether of fraud or fraud, because we still do not have proof of authenticity, but I will not hold Tether long, it is too dangerous.
Now you have said the reason why they are still staying on top, because everything has always been pure speculation and not fact, when news is created based on speculation and there is no proof or whatsoever t backup the claim, then it becomes very useless in having any negative effect on the project.
If tether were really behind the pump of BTC is 2017, then why have we not seen its effect again, since it is so easy to manipulate the market of Bitcoin, to me, tether has served me better than what it is out there written about it, I just see it as mere FUD news that is not true to displace them of their 10th position.
