Fair enough, for now, but what happens after this upcoming halving or next halving when the BTC blockchain reward isn't large enough to convince financially savvy miners to continue hashing when their mining costs exceed their rewards? Sooner than later it's going to happen. Transaction fees must replace rewards as the means of sustaining the security model. How large do these fees need to become on BTC at only 7 tps???
This doesn't have anything to do with BSV. But to answer your question, we'll have to wait and see as its an unprecedented issue. For the next couple of decades I think it will be a non-problem. The current hash rate for BTC is incredibly high. Its fine if it drops a couple orders of magnitude; Bitcoin will still be the most secure blockchain several times over. All other PoW coins combined don't come close to matching the security of its chain.
