The positive thing about BTC is the up coming halving, till may I am very bullish on the price, what people need to see now is that the market is maturing and more patience is needed to reach ones goal. As for Altcoins, I don't see future with many of them because I feel time as come to see the shitcoins die
Altcoin will be affected too when bitcoin price pump after halving i;m sure about that because people won't just stick with bitcoin when they already got much profits, they must be pump another altscoin (good alts only ofcourse) so they altseason should be coming later on
