Is There a Centralization Pressure in Bit Coin?

In 20 17, there were big debates being had about bit coin and whether there would be centralization pressure. Some of the different arguments i heard were that minor the additional latency caused by larger blocks would cause miners to have a centralizing pressure. Hee, so then i guess it's the argument essentially, then, that it causes this centralized like i guess, bringing it back to what's the problem, right? So think centralization of the crypto currency is obviously an issue. Did you want to elaborate on any of those ideas in the bit coin context, for, say, 20 17, before we then compare itback to what's going on in ethereum,. yes.
