Can someone tell me why the Alt coins price is affected so much my bitcoin price? I feel.like I'm investing in excellent altcoin projects but due to bitcoin they just seem to plummet........argggggg. Many thanks in advance
Bitcoin is a leading cryptocurrency so market sentiment depends on bitcoin prices. If bitcoin prices go up then altcoins will come down because people sell altcoins to invest in bitcoin and if bitcoin prices go down again altcoin prices will come down even worse because people think that market is crashing but altcoin prices go up only when bitcoin prices stable.
If you have invested in a good project then don't worry about the current market price, just hold them and when the market recovers all good coins mostly recover faster than shit coins.
