The main idea of a stable coin in itself is a big step towards a safe blockchain ecosystem. Currently, many new entrants who cannot afford the capital or volatile market buy these tether as a reserve and then use it later as the price is stable to the dollar.
However there is no provision to mine the token which might not be a great idea, but to keep the tether valued at $1, it is the necessary step.
Tether aims to represent a digital cryptographic value equivalent to Fiat currency, US Dollar to be exact. Tether token at the core is very much a cryptocurrency, with features such as the decentralized form of data storage and processing.
However, what makes it distinct in comparison to mainstream cryptocurrencies such as Bitcoin and Ethereum is it centralized emission and the rate which is always kept at an equivalent to one dollar.
In case of any third party wallet, there will be charges as set by the third party wallet system. A user still needs to pay a small amount over fiat deposition, usually 1 USD. The advantage of sharing money over the USDT network is that people won’t suffer any loss of fund due to market capitation as the value of USDT is fixed.
