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.
If I had the money I would invest in all top 100 coins in coinmarketcap. But useless to say I don't have the money

Be patient for a while, and hold your coins and wait for the bull run. I am sure you will be able to have much money, so in the next future, you can invest in all top 100 coins in coinmarketcap. But for now, if you have money, it is better to buy a cheap coins price and hold it as I say, but you only need to buy a profitable cheap coin which can give you a big profit in the bull run. You might need to analyze that coin before you buy.
