Keep accumulating over the long term by buying at dips. Always keep spare cash to buy the dip just in case one occurs.
Usually we run out of money to buy any more during a prolonged bear market. This ends up having a bad effect of the traders. The solution is to stop trading for a while and just observe the market for the return of the bull market. Spare cash remains spare only for a short period.

Currently the prices seem to be inching towards 32k which means the bulls are returning to buy or some big players have bought bitcoin. I am expecting a bigger dip to happen in case some other player sells at this point or the trend to continue. So this might end up being the fresh start from this bear cycle.
Cost averaging is good, but buying at every dip should be done with caution so as to not end up spending too much. Lower than normal prices may arrive, but you have to patient.
