I have seen several posts about how ETF and Bakkt could make the crypto market bullish again. As much as I really want the ETF and Bakkt, I really don't believe they will moon cryptocurrency. They will definitely cause the market to be bullish but they won't make cryptos to moon to a new all time high.
What I believe will moon cryptocurrency is the next coming Bitcoin halving.
Looking at the past history and chart of the crypto market, there have only been two halving in history (2012 and 2016) and both resulted in a powerful bullish trend which took coins to a new all time high. The next Bitcoin halving is scheduled for mid 2020, and it will have a powerful bullish trend on the crypto market.
