The protocol governing bitcoin is design in such a way that the rate of supply of the coins is in deflationary way. It was designed that every 4 years the amount of bitcoins will be halved untill total amount of 21 million is reached.
As at now over 15 million is in circulation and the next halving is expected by july. This as brought in a lot of talks in the bitcoin community about the effect of this on the price of bitcoin.
Many are hoarding their bitcoin in the hopes that this halving will bring about scarcity thereby making the price to skyrocket. while some differ.
I am of the opinion that the best approach is to aquire good altcoins at this point so that anyway the ball goes, it will favour you all the same.
