Although bitcoin continues to be mined, in the grand scheme of things it is a deflationary coin.
With a 21 million hard cap, every time coins get burned or lost or locked out, it decreases the overall supply.
IT's more useful as a store of value like gold, than for day-to-day and micro transactions.
exactly you hit the nail on the head.
To add to this as the overall supply decreases then, in theory, the value should increase especially as more 3rd parties accept bitcoin.
I'd like to think there will be people writing in their bitcoin wallet and key information in their wills to pass down to their children and I'm sure that can and will happen. The amount of coins will decrease to some extent because not everyone is willing to do this, but with a 21 million coin cap? There will always be a fair amount of them left.
