We are still early
In Bitcoin journey yes but in Bitcoin blockchain reward in proportion to its initial reward (not the time frame of reward halving schedule) no. The next halving will decrease the block reward to 6.25/2 or 3.125. That is way smaller than 50 BTC per block. So I consider the reward journey in terms of total circulating supply to mid late period. The following Bitcoin mining after two or three more halving is almost negligible. See the percentage limit, it is on the 96% of Bitcoin supply. This means Bitcoin is almost mined up. And that is not an indication of early period in terms of mining and block rewards.
