You get a point there because each time the Bitcoin market makes any move the impart on altcoin will be huge and this has led to the death of many weak coins/tokens in the past, Bitcoin has been the big player in the market and Bitcoin is also the determining factors of the entire cryptocurrency market, so any time Bitcoin dropped significantly altcoin also follow the same pattern but with higher devastating results on the market cap of most altcoins.
