I don't really agree here, you don't need to increase your capital. You can just even preserve your capital, and do proper risk management. Protect your capital at all costs, like always do have stop losses. Always think that not most of the time is a good to trade, sometimes you need to wait for better trade entry.
An accumulation strategy by placing an additional budget to trade without selling assets beforehand may seem a good one to consider. The intent is clear, but it's not the only way to maintain profitability.
Growing capital and maintaining profitability is very difficult when the market is as volatile as it is without an additional budget, but I agree that sometimes traders don't need to push to get in if the market is so volatile. I've been practicing the strategy, it can recoup your capital losses from falling prices when the recovery occurs, but may not be suitable for those who have no other income for a extra budget.
