why do you only want to focus on coins that will have the best short-term gains. Everyone who gets involved in the crypto markets is always behind making short term profits, asking what's the next 10x and 100x coin.
On the contrary, 100x trades are usually long term holds. More than a year. With these kind of whale trades, you're looking to get in on the ground floor, when a coin is not on anyone's radar, has a micro market cap and isn't trading on any major exchanges. Think about coins like DASH or Decred. Long term holders are sitting on massive gains. No need to sell for short-term gains. Like BTC, the strongest coins never return to the low prices of the early days.
How can anyone on this forum know that for sure, no one can answer with certainty. What I would reccomend is that you start focusing more on what the project actual offers to the community and to the token holders, whether it offers any real value and how that value will translate eventually in descent returns. You will make your 100x coins if you start asking the right questions, it's irrelevant which coin will make the most profits in the short term, try to focus on long-term growth which is the most sure way of making 100x returns.
Indeed, that's what I'm getting at. As an altcoin daytrader, I'm looking for a 2x or 3x gain. As an altcoin investor, I'm looking for a 100x gain. Or maybe even 10,000x. Gotta keep an eye out for those gems.
