Why are hard forks planned every 6 months?

Every single piece of security software you run has to try force security updates, otherwise you could be running a trivially compromised piece of software. Most closed-source software, and even open-...

As I understand it the reason for the scheduled forks is to avoid the plight Bitcoin now experiences, where politics trumps tech, and forks are used as a way of derailing features and progress. It ...

Are there any technical reasons why Monero Classic could not exist?

No reason. Some did just that (probably not intentionally, though). You're free to mine on that chain, I think it's still there. You could make an exchange and sell those monero if you wished (...

Why will the v5 fork raise the min block size to 300,000 bytes?

@Jollymort will probably answer this better but the current dynamic size algorithm didn't work well with RingCT transactions. It worked well with non RingCT transactions, which were smaller. Once a ...

How will the ring CT fork be rolled out?

Does it mean that no upgrade will be required prior to RCT HF? This is currently correct. However, Ring CT is also in a testing phase on testnet. Therefore, there exists a possibility that bugs are ...

As a XMR recipient after HF4 is there a way I can only accept RingCT payments?

If by "reject", you mean prevent that transaction from being mined and being available to your private key, then no. If by "reject", you mean only act on rct payments, then you could ask the client ...

Is it possible to increase the total supply and how equally distributed is monero among it's early adopers?

Is it possible to change the total supply afterwards, by a Hard Fork for example? That would be possible, but it would break the social contract. I am quite certain almost all community members and ...

Is there a risk that cold storage wallets containing non RingCT outputs will be unspendable in the future?

This answer is assuming you are on any 0.9.x version (lower versions would already have been booted off in the previous hardfork) currently. Note that 0.10 is going to be released soon. In general it ...

Why is 10.1 a mandatory upgrade?

10.1 has a fix for RingCT. Changes have been made to 10.1 nodes to fork one block before 10.0 in order to avoid letting anyone use the flawed RingCT code, so Miners need to make sure they mine on 10.1 ...
