From the last three months prices of Bitcoin are range bound and hovering around 3600$ .It seems that the prices are settled and waiting for the uptrend movement . Is it the start of the journey towards 20000$ again?
Your theory is kinda stupid.

The prices aren't waiting for anything.The whales are waiting,which leads to all the other traders waiting.
The market is waiting and this helps the bears,because if they start mass selling btc,the price will go down for sure.
Yeah, it's more of the other way around and as we can observe with what's been happening the last 48 hours, it's by far not going upwards. We may yet see another new low since the 2017 run. A stagnant movement in a price this low can take the guts out of potential new investors.
Even tough I think prices are not going up soon (it could, it might not, we don't know) I also think you are wrong too. I mean just because price is low and it dropped a bit doesn't really mean it will continue to go down. It can recover and go up by a big number as well. Hence I think we should say that we have no idea what will happen to bitcoin.
The real problem comes with the uncertain things if you ask me. If we know what will happen in the future (even if not the price but everything else) we can calculate what the price could be, however during bitcoins life there is always unexpected things that happen changing the price and honestly there is absolutely nothing we can look forward to that can take the price higher or lower hence we are just "waiting" right now.
This theory can be stupid, prices can drop more before they start to rise, anyway we cant deny positive side of this comment, lets be honest its what everyone with some coins wish to happen. This world is very corrupted, 10 years of crypto are to short, we need more time. Do you see governments across the world, what banks do in every country, who can tell me that this world is normal when kids are dying from starvation, people are still slaves, working for couple dollars, while some people are billionaires. Crypto can change many things, will it happen or not its a big question, we will need to wait and see, but I hope for the best.
