So let's say BTC was to be absolutely frozen from here on at todays price ,would you still buy?
No, that would be a highly suspicious thing to happen. With so many exchanges running a sudden freeze of market price is clearly a remote possibility and a panic producing one.
I don't think BTC was intended as the speculation tool it has turned into .
Does it really matter what people use it for? Fiat is only used for transaction but you get into FOREX too. Similarly bitcoin can be used to buy/sell altcoins or fiat. The more uses an asset gains the better for the asset only.
Being a deflationary currency and a censorship-resistant one, it is bound to have leaps in price and therefore chances of speculation.
Who on here regularly makes purchases using BTC ?
If you buy everyday, you will eventually run out of liquid cash at hand which is needed for everyday purchases. This is less if your country has merchants accepting bitcoin so buying it would be practical.
You should buy at prices that you know are support levels or if the market crashes. Not everyday because the price on those days is never predetermined. That is a foolish thing to do.
