The developer claims that with such characteristics it would take 584 million years to produce the equivalent of $1. For comparison, the performance of the Raspberry Pi 4 microcomputer is up to 200,000 H/s.

People and businesses have been using "stabelcoins" more often because they are less volatile than other cryptocurrencies: their price, due to their collateralization with real assets, should not fall much following the collapse of other digital assets. The decline in bitcoin's share of payments could also be due to its 40% year-over-year rise in price, Bloomberg suggested: many cryptocurrency owners decided to save it instead of spending it.

Recall that Cardano (ADA) was hovering around $1.26 before last weekend, and hit a high of $1.5020 this morning, up 20% in 48 hours.

A possible reason for Cardano's rise was the news regarding the officialthe announcement of the launch of Pavia, Cardano's meta-currency and gaming project NFT, via a widely circulated press release that was titled "Meta-currency has hit the Cardano blockchain."

Pavia is an NFT gaming metacurrency that positions itself as a direct competitor to popular cryptocurrency metacurrencies such as Sandbox and Decentraland.

Each plot represents a unique Cardano NFT (CNFT) number based on coordinates in".

And while the Pavia meta-universe uses its own cryptocurrency, $PAVIA, rather than Cardano, the latter's rapid recent rise was more a reaction to this news as a result of the association of the Cardano name with the meta-universe concept than an expectation of a further ADA rally.
