Just looking at this pic below makes me unsure about anything and totally having no idea what's going on.
When bitcoin price decrease, altcoins used to go up. But now it's a full go down down wave which me really anxious waiting to find out where all this is gonna end.
It's a bumpy road but it's worth it.
OK I will try and explain this is as simple as possible;
When the total marketcap decreases all coins decrease in value
When the total marketcap increases all coins increase in value
When the total marketcap stays the same and bitcoin decreases then altcoins increase
When the total marketcap stays the same and bitcoin increased then altcoins decrease
