The right after the BTC(Bitcoin) 4th halving, BTC block rewards for tx(transactions) fee had been much than now. Now, it's much less than that time.

If this situation continues, some BTC miners may move their hashrate for mining BTC to other POW(Proof of Work)-based blockchains. It looks like a stress test for miners. It would be a tough time for a while. Fasten your seatbelt until stablizing block rewards.
