I hope that you will make a profit and that you will not have any loss, but halving time is not a time when the price can double during the short term.
It is true that the supply is decreasing and the demand is at the peak, but some mining devices will exit the market and the last parity will be achieved within a period of one to two months, during which if the demand increases, the price will increase, otherwise there will be no change.
Price can be manipulated before or after a big event. If price always goes up, doubles before a halving or only moves like this after a halving, the market will be easily predicted. Whales who manipulate the market will not do it like this so I agree that buying a big Proof of Work altcoin like Litecoin around halving time when its price has yet moved up too much is a good choice.
I must warn that guy about risk, like you said, don't expect it will move up immediately after you buy it. Don't buy it with leverage and speculate its bull run.
