We don't get confirmations about turn-over. Many people want it but it can be trap. While BTC price don't break $4400-4600 down-up we can't tell about stable global uptrend. I think we will see many FUD till it will happen
We will be sure if bottom is reach and bear market is over only after bull market will start. And bull market usually start at least 6-12 month latter as bear market finish. So we will basically not really be sure, if we reach bottom this week, or we did not until the end of 2019.
