Not surprising to see that since every altcoins out there has followed the track of Bitcoin. So instead of wasting your time and money for thinking about holding shitcoins maybe more better for you to buy Bitcoin directly since you would see more reliable coins that can possibly bring you some good profits.
Although many may say that alts bring high rewards but still people need to realize how fast the dump and pump scheme happening there and its unpredictable that's why chances to lose is so high.
So better pick the best and eliminate the thoughts of buying shitcoins.
With bigger caps, there is no pump and dump there.
But I agree, many track back to BTC how the ocean waves, and they get bigger pushes from such moves on it.
That's why there is a BTC rally and only then - an alt season for a brief moment, and it all starts anew.
