Knowledge is basically not enough without proper wisdom. Only with having both knowledge and wisdom can one be a better doer. Just think about it, what would knowing help if you do not understand the ways to apply the knowledge you have or when you should apply it? In contrast, only understanding the ways won't do you any good without the concrete knowledge to back it up.
Things are not even in wisdom, but in discipline and understanding of how to apply your knowledge. Just do not need to complicate for yourself, what can be done simply. For example, we see that in the long term, bitcoin and gold are constantly growing in price and it is not difficult to guess that this is due to the constant increase in the money supply and rising inflation. Therefore, there is no problem just buying bitcoin and gold and waiting for them to grow in price.
