The perfect moment is the one which can be considered as potential for investing when the market is falling. When the market drops, people begin to buy coins, this leads to price growth. Some may reach ATH. I agree with you. Your list looks like this because they are the goal of many investors.
Also, you can choose the coins from TOP-100 CMC. Almost everyone recommends coins from this list because this is the best way to invest. Never invest seriously in new assets.
