Those are some great points, @rcebike. I honestly have more understanding of Steem than I do Bitcoin, so I'm not sure how much control the miners really have over the future of the blockchain. I don't believe that BTC blockchain changes that much unless there's a fork. And with Steem there really are no forks but rather changes that can be made to make things better which requires a large consensus of the top Steem witnesses. But again, I'm not as informed about the inner workings of BTC as I probably am with Steem. But you're absolutely right; there are only a handful of companies now that can actually compete (or afford) to participate in the mining of BTC. Great points you've made and things to consider. I appreciate it!
