The halving is a significant event, but people should not only look forward to it, because they know the price will increase when it happens. It is a marvel to admire because Satoshi anticipated that we would need a halving every 4 years to increase the rarity of the coins. I do not think that there are any relationship between the halving and previous spikes in the price.
I am just happy that we are still receiving a lot of coins to buy and this is something to celebrate.. as time goes by, less coins will be available for people to buy and we will have had a good opportunity to buy coins before all these halvings.
