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
I would say it is already positive even without the halving coming. Bitcoin even at the rate of current rewards is still getting harder and harder to mine every day with difficulty just increasing to no end. Imagine when 50% of that reward is gone, miners need to keep making money so they will sell only at a profit,,, which will drive price up!
