1. Restrictions from the government and regulators who keep on threatening that they may ban bitcoin or crypto in general anytime, imposing an unjustly ridiculous tax on trading and withdrawal literally leaving us with loss even if we make a profitable trade. What if a situation arises wherein we cannot withdraw even if the value of bitcoin increases as it will be of no use.
Even though the government bans Bitcoin, it doesn't mean that the flow of funds can be stopped easily and even if it is tracked, it will only be dealt with by centralized exchanges. Otherwise, the government will not be able to move freely by limiting taxes on Bitcoin. Cross-border transactions will overwhelm the government and we can still easily circumvent its policies.
2. We need to earn a lot before hodling as most of the users in this forum are joining campaigns where the payment is not even guaranteed especially bounty campaigns so I hope you understand the financial situation of people which is due to unequal wealth distribution created by corrupt government and this can be broken when people start earning more through various source of freelancing instead of 9 AM -6 PM job which has made them slave and only once a person has a good amount of at least $100-$200 (this might be little for us but for people from certain geo region this is way more) they can invest and hodl or trade.
You don't need to have a lot of income, that's just about ideal. Everyone can have the amount of Bitcoin they can afford to hold and not have to worry about consistency methods. Because doing it in a way that you can afford is the right decision rather than having to wait for something that never gets done at all. There are no specific rules for holding Bitcoin. Buy as much as you can and hold on as hard as you can.
3. We need to buy in dip or at the peak of a bearish market if we want to buy and hodl for at least a few years, we can take the example of people who bought at the peak of bull run during end of 2017 and had to wait till the end of 2020 to meet break even and gain profit but many end up selling due to panic and fuds, we need proper channels to educate users to avoid panic selling and build a strong community as a lot of negativity was spread during last bear market which distanced many from crypto.

Buy The Dip is simply a set buying limit, and sometimes it relies on investors determining their trading lines against a long-term benchmark. Holding for 3 years from 2017 to 2020 may be a bit disappointing as it was bought at the start of the bull run. However, the profits will be much greater if you can hold it up to 2x ATH.
