Connected between ethereum and bitcoin because when bitcoin keep on fire with higher price ethereum always allow how bitcoin going on, but when bitcoin going down never for hold and invest etehreum because price keep going down too allowed what happen with bitcoin. I think ethereum the only one coin always allow his condition on bitcoin and never growing up by self without waiting for when bitcoin will grow up and have good price, impossible seeing ethereum cross above $1000 without get bitcoin could reach above $20k and never take profit for ethreum investment if bitcoin keep lower price always.
These coins have no connection with each other because they were created for completely different purposes. Bitcoin is the most reliable coin of the entire crypto market, it is in it that savings are stored and they wait out times of crises. Ethereum is needed to accelerate the launch of new projects, including fraudulent ones. It is because of this that its price is more prone to jumps and falls.
if there is no relationship then how can cryptocurrency price movements depend on bitcoin price movements? so I think even though there are some tokens or alternative coins that have nothing to do with bitcoin but bitcoin is still number one.
