I like how you think. I think along the same lines. I spend a lot of time on coinmarketcap looking at 100 to 300 trying to find the up and comers that i can get in at a great price before everyone else gets in and drives the price up. another thing i do is , when the market cap decreases, almost every coin goes red. find the few in the green and watch them. thats how i first found two of my favorite coins. I found them before the segwit2x fiasco when all altcoins were down they were green and they have over tripled since.
