One advantage of stablecoins is price stability. Merchants don't have to worry about price volatility when transacting in stablecoins. In the past and present, there have been a handful of projects proposing issuing altcoins (non-stablecoins) that will lead the future of crypto payment. What's the fate of such projects, will there ever be considered viable?
Stablecoins are pretty handy, and the fact that Stakenet (XSN) is a cross chain compatible via the Lightning Network, means that anywhere where BTC Lightning Transactions is accepted as means of payment, means XSN is automatically accepted.
Same goes for stable coins, with USDT support, you can cross chain swap XSN for USDT over Lightning instantly.
Stakenet is unique, as it benefits and enhances the whole BTC network, unlike other projects trying to be "the better BTC"
