Yes as you say, it's the perfect method, because right now I feel Ethereum, Bitcoin, all those "big" coins are way too expensive and it's no longer worth it, especially with the high fees, you won't start thinking about making profit before a long time with the crazy prices right now. So let's better look for the best entry point as you say and find the next Bitcoin ! This is more realistic, the quest is harder, takes more time but if you do find it it's definitely worth the painful hours you spend on it. There are dozens of ICOs created every single month, or week, so all of them are offering interesting offers like free coins, things like that, I prefer sticking to this, because you know you won't lose much but you can gain a lot soon :D; that's what I prefer writing about, all those ICOs or developing coins that can have the potential to burst.
