Regardless of whether March is not so great to expect price hikes, in reality we still don't know.
I just don't think you should worry enough about short term price volatility because basically not everyone expects short term gains. Even if bitcoin can break below the $20K support, then that will only give long term traders and investors an opportunity to get one more dip to buy.
Just invest and hold on brother, it is one of the best options to prepare yourself for good benefits in the long term. I have had this belief from the start, and it should be shared by other users as well.
I agree that it is not going to be based on the previous years, just because March was good or bad, doesn't mean it will stay good or bad. I have seen plenty of times when things changed, even that chart alone shows one month being great one year and not so great next year.
It's really hard to see any pattern, I agree. It's like no one see the future and know what is gong to happen for March. We will just have to base everything on pure speculation or what we are seeing in the market right now.
This is why I think it is important to take what is happening right now into consideration before we could go on. In any case, I believe that it is going to be pretty tough to overlook the fact that we have gone up decently, forced to backdown a bit, and we are going to keep trying to go higher more and more. Obviously it is not going to work for the quick term or anything, but it could probably work a bit better long term.
So far though, market remains to be bullish, we have seen the price dropping significantly and we always recover from those bout of suddenly free fall. Now we are still above $23k which is a good indication that we are still very much bullish for this month.
