An ETF approval and 2020 halving will help the bitcoin price appreciate.
No, I dont think so because ETF is a flop idea and most people are not interested to invest their money in ETF. Bitcoin itself is not popular yet in the entire world, how ETF will succeed. I do not understand this thing. People should be motivated to invest in bitcoin instead of ETF, it will be much better than anything else will. High sell of bitcoin will push bitcoin price upwards.
