The bitcoin halving is going to affect the supply but the effects are not going to be felt immediately, besides each halving is getting smaller so the effect on the market may even need more time to be felt than what happened in 2016, if anything I agree with the prediction, many are expecting a bullish year of 2020 not realizing this was the bullish year and most likely the next year will be one where not much happens except a slight decrease in the price of bitcoin.
Yeah, we can't predict how the market will go until entering the halving stage. so according to the schedule, it will start in May 2020. So bullish season we can see after that, until 2021. but for the price, everybody predicted, it will touch more than previous ATH.
That is what I am expecting as well, everyone wants to see a price increase that happens immediately after the halving and we need to be smarter than that, the market of cryptocurrencies has never been that predictable, what it will most likely happen is that there may be a moderate increase in the price and nothing more, then some people are going to be disappointed by the lack of growth and the price will decrease, and finally at some point during 2021 we'll see the growth we wanted.
