In 2020, circulation will continue to be the main challenge for all cryptocurrencies; one of the best ways to boost circulation is through gaining acceptance at major e-commerce websites, and this is something that the controversial token known as Tether recently accomplished. The next time you book a hotel room on Travala.com, you will notice the option of making payments with USDT.

Travala.com is a market leader in terms of crypto token acceptance. The company allows payments to be made with Bitcoin as well as various other digital currencies such as Ethereum, Litecoin, Bitcoin Cash, and even Cardano. There is even an option to exchange fiat currency into the company's very own token. Despite this friendliness towards the world of cryptocurrencies, acceptance of Tether has raised some eyebrows, particularly because Travala.com is a partner of Booking.com, a giant of the online travel reservations segment.

Here's what makes Tether such a strange bedfellow for Travala.com: The development team behind USDT is facing a major lawsuit filed a couple of years ago by the New York Attorney General; the crux of the complaint is an allegation that Tether was used to inappropriately cover losses of a major cryptocurrency exchange platform. There are strong doubts about the cash reserves of Tether, which is a token pegged to the value of the United States dollar, but the daily trading volume of USDT is very strong nonetheless.

As the original stablecoin, Tether has managed to create an interesting financial purpose. Companies that accept digital currencies are known to convert payments received immediately to USDT; this is done for the purpose of managing volatility. Travala.com is one of the companies that engage in this practice, thus making its decision to start accepting Tether more sensible than controversial.

It remains to be seen whether USDT will be able to retain its position at the top of the stablecoin totem pole. The main competitor is USDC, a token backed by investment banking giant Goldman Sachs, but there is always the risk of the United States Treasury one day deciding to run its own blockchain in order to provide a digital version of the dollar.
