turning $10 into $100 in 3 days (a highly speculative goal), you should look for coins that are prone to short-term volatility or potential pumps. Here are some options, but remember this is extremely risky:

1. Meme Coins (e.g., Shiba Inu, PEPE, Floki Inu) – These coins can experience massive, short-term price swings due to social media hype.

2. New Listings – Look for coins that are being listed on major exchanges or have just completed an ICO/IDO. These can see a price spike right after listing.

3. Small-cap Altcoins– Coins with low market caps (e.g., GALA,Celo,Kishu Inu) often have higher volatility, which could result in large price moves.

4. DeFi Tokens– Some DeFi projects (e.g., Sushi,Swap,Aave) can pump due to announcements or market sentiment shifts.

5. Leverage Trading – Use margin or futures trading (if you’re experienced) on platforms like Binance for amplified short-term gains (and losses).

Again, this is high-risk and could lead to significant losses. Never invest more than you can afford to lose.
