Only for awhile tho. Sooner or later more countires will adopt BTC increasing its price. And solutions to work for transaction time, block size and transaction fees are in works. Lightening network nodes testing is going well so far, segwit adoption getting traction as well. Once they work out, and BTC mining reduces to 6.25 next year. BTC will see a sure shot hike of 50% in price.
the block reward decrease is not the main reason for an alleged (and expected) price rise
to me it is pretty obvious that the negative news surrounding bitcoin and crypta in general
are too well timed to be a coincedence,the price had to be driven down after the crazy 20.000$ mark has been reached
and it is down now,dancing around 11.000$
segwit adoption is another fairy tale,only 12% of transactions are Segwit at the moment,it may take another 2-3 years to adopt fully if ever
Lightning network same,so if the price is going up it is not due to the tweaks in the code,but due to supply/demand or
the market being played by the powers we don't see,same as with the oil,gold prices etc.
these are too important to let some "free market" to decide
again it is just my IMHO and the reality could be much simpler and less interesting
