Note that cryptocurrencies (typically?) don't have an official exchange, the official thing is that you get compatible software, might need to download the entire history of the network, generate a wallet (which is a local cryptographic process), and allows you to issue transactions from that wallet (and presumably other funky actions)
Whatever you used that required 20€ minimum was presumably just some exchange... Though scams are very commonplace in cryptocurrencies. Probably a good idea to avoid them unless you have a specific need and you understand why you'd need specifically crypto for something.
Disclaimer: I don't actually use crypto and can't give you specific recommendations, but I think the technology itself and the idea behind it are cool.
I see, i guess i got scammed or smth :/
Yeah i agree, though, I think that's not a good tech anymore and hopefully it will superseeded by tech similiar to the digital euro one which seems way more reliable and works offline
Huh, that's curious, that sounds impossible to make properly secure, since if you're not verifying the validity of transactions with some trusted third party or ledger (I think it's called that in crypto), someone could make a transaction, and then locally rollback their state to make another transaction to somebody else, which wouldn't actually be valid.
I'll have to read up on it if I remember, maybe it's just half-offline, in that you can sign transactions offline if the other party is online to execute them?
Generally though, whether it's "good" tech is a rather ambiguous question - I think it's a good concept that has some ethical problems and big issues in practice, including social aspects of how it's used. I think most people on the fediverse value decentralization to some degree, so a world where crypto didn't end up being mostly used for speculation and scams could've been interesting.
