1) It still does not affect the overall total number of bitcoins there will ever be, it just means some are mined sooner than expected
2) The mining hashrate has been increasing at an exponential rate, which is what led to the mining being ahead of schedule. The exponential rate cannnot continue indefinitely, when it does, the rate of bitcoins being mined will slow closer (or even below) the schedule of 3600 per day.
3) The extra coins being mined, increases the rate of Bitcoin's supply side which actually keeps the price down if anything. For example if the miners are selling all their mined coins every day, that's maybe 4k hitting the market instead of 3600 - an extra 400 coins a day selling pressure for example.
Taking into account points 2) and 3) tells me that the current selling pressure by miners is likely to be more now than it will be in future, this is encouraging for hodlers no?
