Tether (USDT) is the world's largest stablecoin. It is one of the top five largest cryptocurrencies by market capitalization and has been trading in the cryptocurrency markets for over seven years.
While there have been some controversies surrounding Tether's US dollar reserves in the past, the company has made a point of providing regular proof of reserves to ensure that traders and investors can be confident that money held in USDT is safe.
Tether is critical to the operation of the cryptocurrency market, making it one of the crypto space's "too big to fail" projects.

Holding Tether (USDT), a stablecoin pegged to the US dollar, can be relatively safe for short-term transactions or as a way to avoid cryptocurrency volatility. Tether is commonly used for trading or parking funds between investments without converting back to fiat. However, there are risks to consider.

Concerns around Tether's transparency and backing reserves have sparked scrutiny although it claims to be fully backed by assets, some regulatory bodies and investors worry about the nature and accessibility of these reserves. Furthermore, Tether is not immune to regulatory actions or changes in policy that could impact its stability.

For long-term storage of value, other options like traditional fiat or regulated stablecoins may offer greater peace of mind. While useful, holding Tether requires careful consideration of associated risks.
