No. There is nothing to withdraw.
The coins in your portfolio are demo currency. They have no cash value, they were not bought with real money, and they cannot be converted into money, crypto, vouchers, or anything else. A profitable simulated trade increases a number in a practice account and nothing more.
There is no deposit function either, for the same reason. Finoha has no brokerage account, no wallet, no custody, and no payment rail pointing at you. The only money that moves is your subscription payment, going the other way.
If a website, message, or person tells you that you can withdraw Finoha profits, convert your coins, or "unlock" your simulated balance by paying a fee, it is a scam. Do not send anyone money, and please tell us at info@finoha.net.
