Why it wouldn't be a saving account? I don't understand.

Which platform offers real saving accounts according to you?
You're wrong mate, Freebitcoin is the main saving account platform for many people, that's why so many users bought FUN tokens.
Unlike many shady custodial platforms we know what is its business model and from where the money comes from.
About savings, I meant the likes of Celsius Network and Nexo as they are financial institutions.
I'm not saying that Freebitcoin is
NOT a savings account, but the branding itself is known more as a faucet and a casino.
