I once tried crypto, I added 10/15€ to the wallet, I couldn’t use them for transactions anymore cuz i needed to add at least 20€, i honestly just left those money there and ignored cryptos ever since; it was not told to me anywhere that i needed at least 20€ for transaction, i expect them to hide even more important infoes about how the shit works if they do not bother to let me know such stuff :/

Edit: i used USDC i think
