about 80 coins on top 100 look good to buy. they may look good to buy but volatility is still volatility. i like top 10 coins alot but still risky to invest no? i may invest in those coins just looking at it everyday.
Of course, they will always look good until you buy them and they discover them going down. The only good thing about those top coins (I would say top 20) is that they may not be easily wiped off during any crash. On the general, I would say only invest money you can afford to lose.
