Well, it's just a hypothetical situation if I had the money like you said:

$5,000: Allocate a smaller portion (20-30%) to a lower-risk established coin like Bitcoin (BTC) or Ethereum (ETH). Invest the remaining amount (70-80%) in a basket of 2-3 mid-risk projects with established use cases and some track record, such as Chainlink (LINK), Polygon (MATIC), or Polkadot (DOT).

$10,000: Maintain a core holding (15-20%) in established coins. Allocate a larger portion (50-60%) to mid-risk projects like the options above. You could also consider a small allocation (10-20%) to a high-risk, high-reward project after thorough research. Remember, high-risk projects have a higher chance of failing but also the potential for significant gains.

$15,000: Maintain a core established coin holding (10-15%). Allocate a larger portion (40-50%) to mid-risk projects. You can explore a slightly larger allocation (20-30%) to high-risk projects, but prioritize in-depth research and understand the potential downsides.

Since the priority is to get more profit in a short term, the majority of my investment would not be focused on Bitcoin or other top altcoins. Additional tips: Always DYOR (Do Your Own Research), don't invest more than you can afford to lose, and avoid FOMO (Fear Of Missing Out).
