Currently, Bitcoin has undergone three halvings, namely November 28, 2012, July 9, 2016, and May 11, 2020.
The recent LTC halving of the same type entered the hype expectation half a year in advance, and then entered a decline.
On the other hand, the current expectation of BTC halving does not seem to be hot, but it is a good thing for the rise of the market.
