It is good to have investments now while the price of bitcoin is low. It is better to hold your coins and wait that market while recover again.
There is no ambiguity in that. Both of these suggestions stay in favor of the investor. The low cost of the investment helps expand the marginal profit that the investor earns in each unit of coin and the decision to hodl long is another way to let your portfolio gain worth without falling prey to emotional decisions that are often made when the market price falls and the new guys panic about it rather than thinking of a secure way out.
