So the bubble will explode once the last Bitcoin will be mined?
What bubble?
The last Bitcoin won't be mined until the year 2140 or so.
And at that time, miners will be profiting from transaction fees.
That's cool, but I can't understand how it is possible that you don't see it: no more mining -> no more secure network -> manipulable transactions.
Also, you state the last one will be mined in 2140. I don't know if that includes the Moore Law, but even then, it probably doesn't include possible (or probable) biggest jumps in technology, like quantum computers, that are right behind the corner. They could be available in 10 years probably (if they are not already, I know there are some going around but people are not sure they are quantum).
Who said no more mining? You misunderstood.
Re-read what I said earlier: You ALWAYS need mining.
As long as Bitcoin exists, a miner will mine a new block
about every 10 minutes.
I think you are confusing mining with block rewards.
They are 2 different things. Successfully mining a block gives you
a reward, but that reward decreases over the years until
there is mining with no block rewards.
The block rewards (new bitcoins) will stop being
issued in 2140, but there will still be transactions,
blocks, and mining... just no new coins. Got it?
(Moore's law has nothing to do with any of this.)
