Buy as much as possible and hold it until a big spike occurs, the bears are still doing something that can give traders a chance to get a big discount, a good opportunity to add to the Portfolio list. Long-term plans can be adopted while the bears are dancing in the cryptocurrency market, taking the opportunity when more declines from spikes can be made gradually. No need to be afraid to lose, traders who are willing to take risks will get several times when the bulls come.
It's not very effective to buy as much as possible in the same price but make gradual purchases, because the market will not be predictable to fly or fall in the next week, so it's better to apply the DCA buying method to minimize high losses if the market movement drops drastically.
