Investing and holding Bitcoin is always beneficial and does not matter the market condition. Although there are several ways to accumulate Bitcoin one of the recommended ways is to do DCAing. The current market condition is just a phase as after those big gains profit booking was going to happen. In the past before halving Bitcoin would always go through a major correction this might be another correction on the cards. Or it can be a temporary phase as the demand to buy Bitcoin is growing whereas the supply is limited for now. After halving the supply will be lower than now but the demand won't fade away so expect another big push on the price of Bitcoin after halving thanks to spot ETFs.
