Just a few observations:
Top 100 market cap probably won't do 10X in hours, the 100th have roughly half billion of capitalization, if you multiply by 10 it become 60th, not feasible. To reach 10X, or even 100X it is necessary get top 1000 market cap.
Your observation on that is apt. Marketcap is very important. It's the second thing I look at besides max supply of any token, that's also throwing in utility. I encourage anyone who's taking a risk with altcoins to do so. Make a calculation of what you expect, an achievable calculation, and then choose the altcoin that can fulfill that. We shouldn't be greedy in our expectations.
Those low cap coins can only be traded in DEX, get used to Uniswap and related and prepare for a lot of rug pulls.
I thinks it's more difficult getting rugpulled on ETH based projects than on BSC projects. If anyone must plunge into a risky environment like investing in newly created tokens, they should consider more of the ETH enclave projects. For me, I've paid the price of severe loss and ain't scared anymore diving into any chain to seek investment. Profit and loss are the main nature of cryptos. Anyone going into it shouldn't forget that. We shouldn't keep a one-sided mindset that we will always make profit. We should think of the possibility of loss more than we think of profit. That way, we will be prepared to invest only what we can afford to lose.
