Polygon (matic) seems to me to be the most reliable for low cap alternative coins. Low cap alternative coins will suddenly become like Bitcoin in price, but not suddenly. Moreover, they are also very difficult to find out and sometimes they cannot survive in adverse market conditions. And in Bitcoin you don't have to invest much but you can manage a DCA for long term on average. Anyway, I understand your point that you want to make a lot of profit by investing a small amount of money. However, it is wrong to think of the Crypto market as a quick rich scheme.
I agree with you on low-cap coins, especially Polygon. They add an intriguing crypto dynamic. However, the risks must be acknowledged. Due to market volatility, poor management, or lack of utility, numerous tokens have risen and fallen. Sometimes it's hard to find the next "big thing".
The DCA technique for Bitcoin is a proven method for long-term risk mitigation. I appreciate the appeal of high returns with low investment, but prudence is always advised. Cryptocurrency is a volatile market that requires care, research, and patience.
