Cryptocurrency event in Madrid amid regulation warnings

A major cryptocurrency metaverse event was held in Madrid on Saturday. Mundocrypto describes itself as a “world leader in crypto and blockchain education” and says 55,000 of its students have already become investors.

Investments in cryptocurrencies, such as bitcoins, have boomed in recent years but in several cases, currencies have lost their value quickly and people lose their investments in what is an unregulated market.
