>Until somebody invents a quantum computer with a sufficiently large number of Qbits. Then they can completely destroy the blockchain.
That wont be developed overnight, by the time it is a possibility people will be working on solutions. a quantum computer would impact a lot more than bitcoin, all cryptography would become useless.
>Alternatively, wait a few hundred years until you need several hundred terabytes to store the blockchain, which is required for transactions. That's going to be a problem.
With the cost of storage rapidly reducing then that probably wont be an issue in a few hundred years.
>Or you could switch to Bitcoin before realizing that currencies which deflate in value are a terrible idea.
Currencies that inflate have had their share of problems and we certainly have not found a way to solve those problems or the issue of inflation/hyper-inflation. Any problems with delfationary currencies (which you do not detail) are merely hypothetical as no real deflationary currency has existed before.
