the reason is because you forgot to ask why bitcoin price dropped 50% in 5 months ago so now you are confused about why the price is rising back up to where it belongs. none of the things said in that article are correct because the reason is simply because we were underpriced (in a reverse bubble) which needed to be corrected and now it is starting to be corrected.

- Mining Rewards Halvening
we are far away from this to be an actual reason!

-Trade Wars
that's just nonsense because bitcoin is not used in any of this "war" between China and US to be affected by it. you could have used it as a reason only if people were using bitcoin as their import export currency for trading.

- Tether
this is completely irrelevant not to mention that the article is stupidly claiming that people sold Tether for USD and then bought bitcoin with it!!! which caused the price rise.

- Institutional Money
this has not yet happened in any meaningful big scale. it has been happening slowly so it can't be the "new" reason for the "new rises"
