Something worth learning early is how to manage gains, not just how to buy Bitcoin. Decide in advance what conditions would make you take some profit, and consider moving money you've already made into savings or other assets rather than putting everything back into another trade
This is not considered by many because they have decided to be long term holder but, this also has a point of until or how long they're going to hold.
At what price they'll start to sell to take those profits while continuing with the remaining that they have.
As you have planned on how much and when you'll take the profit, also be wise with planning about reinvesting it back to bitcoin.
That might sound funny of doing the two, but that's how the rich gets richer when they know how to manage their capital and profit back to the market.
