''Is it advisable to to have a mentor who I can always go to as a newbie in the crypto space or I should rely all my knowledge on things I read online for my growth.
I don't think you need to spend more time looking for a mentor who will teach you about the world of crypto, even if you intend to pay for it, but I'm not sure that someone will teach you everything about things related to the world of crypto. So it would be better for you to get used to reading everything you don't know about via the internet. Even though it may be a little slow for you to understand, at least you can maintain your privacy with other people regarding matters related to the crypto world.
In the crypto world, everyone needs to take care of themselves quite well and maintain every equipment they use very well for better security, because it is not recommended for everyone to reveal everything to the public. Moreover, if your goal in learning about the world of crypto is for money, there certainly won't be many people who want to teach you for free, unless you yourself make questions in discussions like this via forums.
