What is tether? Tether is a crypto currency that was developed in 2014. It is a pegged cryptocurrency that is suppose to be 1:1 to USD. The idea is that each tether is redeemable for 1 USD. Why would anyone make a cryptocurrency like this? Well its extremely easy to manage and transfer around the world USDT (Tether) rather than USD. Instead of wire transferring or moving another crypto like BTC or LTC, you can move your USD in the form of tether between exchanges very easily like you would move any crypto currency.
So whats the problem?
Two things.
1. Tether said it wasnt associated with Bitfiniex (one of the biggest exchanges) but when the paradise papers came out, info showed that there was a relationship.
2. Wells Fargo (tethers official bank) broke ties with them in April of last year. They said they wouldn't put anymore tether into circulation until they setup a new banking partner.
Since April (especially in Dec), they have created a significant amount of tether (400m total in Oct to 2.1B total in Jan). On Dec 4th, they were subpoena by the US. In Jan the auditor that was working with them, cut ties. They have promised an official audit but have yet to do one.
So what do people think is going on?
Well the issue is that people don't believe they have the USD to back the tether and they have been printing it without collecting USD. People think they are doing some form of fractional reserve banking. On the other hand, some people think the reason they haven't showed the bank accounts or any detailed information is for security purposes and could be related to not wanting their USD freezed. The business model they have makes significant revenue so for them to be a bad actor in the space hurts them as much as it hurts the crypto prices. If your company was subpoena'd would you keep doing something that may be illegal? ramp up? They ramped up significantly after they got subpeonaed which you could make an argument that they would be out of their minds to continue being sketchy.
So why are the prices falling?
A bunch of reasons but uncertainty and fear is one of them. If tether doesn't have the USD it says it has, then exiting crypto to USD will be very difficult. There are several people around examining the creation of tethers with explosion of BTC price. Someone was showing that every $1 tether created, BTC would increase by $10. Right now in the last couple days they have not created new tether which A. means that no one is buying BTC because they are afraid or B. they know the game is up.
What do I think?
Well I want to give them the benefit of the doubt. I also am thinking they should be significantly concerned about their security. One thing that could be happening is they are collecting USD but from anyone (including bad "businesses") which is why they dont disclose their banking partners.
If they come out clean, we will see a 1 Trillion total market cap very quickly. If they dont, we will probably see another 50% decrease.
