Always remember this with Tether, few buyers of Bitcoin know what Tether is and do not care.
Now, let's assume Tether implodes in 101 lawsuits with every Land of the Free Agency trying to un-free it.
What will happen to Bitcoin?
Will it implode? Nope.
Will that 'finally' be the end of the Bitcoin 'ponzi'? Nope.
Will Bitcoin go down in value? Probably. And by how much, could be as much as 20% (maybe more, who knows) but then it will recover at some stage in the future and Tether will be just a footnote in its history.
Now here's the interesting question -
Would proper Bitcoin holders, those who have taken the months if not years to understand Bitcoin, WELCOME a Tether implosion? YES!
Reason, it will yet another test for Bitcoin which it will surely pass (with some likely short term price damage).
Every and any test of Bitcoin is to be welcomed and even demanded because something as revolutionary as Bitcoin SHOULD be tested from every damn angle.
See, the tests and passing of the tests all make Bitcoin that little bit stronger...
PS. And if Bitcoin can't survive a Tether implosion then Bitcoin itself doesn't really deserve to survive.
