I am not sure about the period of 2 months. First of all, if you keep BTC for this time, you are NOT a hodler. You have to hold your cryptocurrency for at least 6 months.
There is no "exact" time that you need to hold for X month for become a hodler. Just sell it when the time comes and buy it when you need to, if you wait for like X month. You are missing a lot of the opportunities if you just hold it. I'd say you could buy Bitcoin right now because they are cheap.
