Anyone can, even a puppy with it's paws, if it can, withdraw coins. However, if bu withdrawing you meant converting to fiat, yes they can, but probably the guardians will be answerable when it comes to taxation as the money will be treated as money earned.
If you are talking about miners, yes of course they can, if they have the coins. But there is no way one can withdraw or transfer or transact other's coins.
No, he meant minor. I've seen this before, at the exchange.
if your account isnt already locked and you are facing a verification challenge, transfer the coins into a trusted adults name that has all their documentation, and proceed. if your account is locked, be truthful with the exchange, and provide proper docs. they can rty to withhold your coins, but remind them they allowed a minor to use the platform without obviously improper KYC.
As far as withdrawal limits, your hands are tied because you wont be able to properly verify. withdraw it slowly, and try to leave at least 100 dollars per day available limit so it doesnt look obvious. Never exceed your withdrawal limit. I dont know which exchange, but it could lock your account and force a verification check.
Thanks you for answering. I'm not a minor anymore but I didn't done any verification in my local wallet aside from email verification. Other verification needs a any government ID which I don't have yet. I've done 1 withdrawal but it doesn't exceeds the limit. I'm aware that if I'm going to cash out a large amount, they wouldn't let me get the bitcoin in the form of fiat money.
Although the TOS usually sounds cut and dry about this, they have a bit of brevity in the documents they can accept for verification. They are strict simply because they dont want people to purposely subvert the rules (assume a fake identity and cash out tainted coins, for example). If you are making a good faith effort with no previous suspicious account activity, talk to them about alternative verification methods. A government ID can usually be a student ID, but it must have a picture. That same national ID, if it has your address on it, can serve for residence verification. And if all else fails, maybe just maybe they will allow you to submit a notarized document to prove who you are. To avoid all that, take my initial advice. Get someone you trust to make a fully verified account, and transfer the value, always slowly, to them for cashing out.
Consider buying a thing in btc, and selling it for fiat.
