-Blocktime 30 min
-Blocksize only 1MB
bitcoin block time is 10 minutes on average (where did you get 30 min from?)
and there no longer is anything called block size. it is not block weight which is 4 MB
and any other cryptocurrency based on blockchain technology which wants to stay decentralized needs to have a limited block size. with 1 sec blocks with no size limit, you will end up needing a super server(s) instead of simple computers run by individuals as nodes. and that is required for a decentralized currency.
