How do cryptocurrency taxes work in Italy?

I tried to wrap my head around it when a friend suggested I invest in crypto, and I have to say that Italy treats capital gains from cryptocurrencies as miscellaneous income: if you sell them and make a profit, you have to declare the gain at 26% substitute tax. The slightly complicated thing is that not all operations are the same - if you hold them for more than seven consecutive days without selling, you don't pay anything, but if you do frequent trading the tax authorities might consider it business income with different rates. It's really worth getting help from an accountant if you want to have peace of mind, because the rules change and it's not exactly straightforward to manage it on your own.
