The core arithmetic of the claim is supported by Bitcoin's halving schedule: halvings occur every 210,000 blocks, so 105,000 blocks remaining corresponds to 50% progress toward the next halving. The fetched article 'Bitcoin Miners Reach the Halfway Point to the Next Block Reward Halving' explicitly states that at block height 735,000 there were 105,000 blocks left until the next halving at block 840,000, i.e., halfway. That same source also states the subsidy would fall from 6.25 BTC to 3.125 BTC, which supports the claim that daily new supply issuance would fall again. I could not directly validate the exact X posts because both fetches failed, so confidence is medium rather than high.
