Well no prediction is accurate and trying to find buttom isn't what should be the concern because we are never going to be certain about that all we do is predict from what chart we have. For the moment we are sure the trend is still down and I believe this month is going to close before a contrary prediction will be seen. I can say maybe we can see more bear to $12,705 but this is just for my personal consumption not an expert advise , trade or hodl consciously.
It's hard to invest looking for the bottom price as we don't even know if its the bottom in this bear market. But seeing the market is really in downtrend, then it's certainly a good time to invest. No need to wait for another market dump, the current price is already cheap and very affordable for us to invest. However, doing DCA can be very useful this time as it could maximize your bitcoin purchase in every price drop.
