Thoughts on effective crypto investment strategies

I am sharing my crypto investment strategy and calculations. It has worked and been effective for me for the past 8 years in crypto. What do you guys think, feel free to add.

My principles:

Diversity: Basically all your eggs are in one basket because everything goes up and down with BTC. Only the percentage move differs but the direction is always the same.

Liquidity: According to your investment size you want enough liquidity to enter and exit easily. Your investment can be worth $10 Million but it is zero if you can't sell it.

Project: Must be delivering some unique value in its use case. Too many new projects popping out with same technology should be ignored.

Accumulation strategy: Accumulating every 20%-35% dips.

Exit strategy: Selling after 3-4 years in a bull cycle.

Coin selection: I segment all my portfolios based on use cases and what are the leading coins in that segment and what are very new coins that are working on an issue faced by these leading coins.

My Tools:

Crypto investment calculator: This helps me check different coin combinations for my portfolio and how the historical performance has been.
