What I suggest is to firstly implement a better difficulty adjust algorithm to protect the chain from potential threat of malicious mining power.
If we can decide the proper algorithm, we can go toward the direction to implement it.
However, I don't like the idea to increase the block size as it's not the necessary thing for Terracoin. It don't need to be popular but it should be secured.
I can agree with this sentiment. The retarget is a little lackluster right now. This could be improved upon. Also, we are still a good bit away from the block halving and there are plenty of TRC that have not yet been mined so I don't see the block reward increase as necessary.
