ok, i thought it was a serious discussion ahha
i hold big on btx, but i would like to know the answers. Always better to find first the negative sides than the positive when you invest

Waiting for someone that answer at this " larger blocks means bigger blockchain, that means less nodes, that means less security"
Larger blocks don't mean necessary a "much" larger blockchain. The thing taking moste space in the blockchain are the transactions and therefore the hashes.
There are many pros and cons on this matter and I'm not going to lay them all out for you. Read yourself:

Your point is pointless, you "need" larger blocks to process more transactions, if you have 20MB blocks but only 50 kbytes of transactions per block your 20MB block size is useless, but sure the block chain wont be any bigger than if you had 50 kbytes blocks. It is a block size LIMIT and if you never even come near the limit the limit is pointless.
