I really want to know why any time Bitcoin increases or go high many other coins will go high too and when Bitcoins drops many coins drops too.
is it that Bitcoin is the backbone of other coins or their is something connected between Bitcoin and other coins.
please I need explanation.
There is a reason on why alternate coins are called "altcoins" because they simply derive their existence on the foundation that BTC built.
Lots of altcoins are present in the market- whether memecoins or usable coins. The latter are the types where they simply took the technology of BTC but they introduced improvements therein. The former are the ones that derive their value based on influence and hype- where its value is totally dependent on supply and demand (ie dogecoin influenced by Elon Musk).
One of the many reasons on why the price of BTC influence these altcoins is because they derive their value somehow on how BTC is performing in the market. That is also the reason on why BTC has the highest price of all altcoins present in the market.
