According to the history, Bitcoin halving really affect the price of Bitcoin, but this will happen in every 4 years. If that strategy you are using meaning you are a long term investors. I'm not against with you because it's your decision and it's a safest time to invest Bitcoin. Personally, 4 years is quite long to wait before you invest that's why since I have knowledge how to analyze the market I used this to invest short term in Bitcoin and some times I do trading.
