Since you mentioned up to 2030 then there is of course a halving in 2028.
Of course Bitcoin will have a higher value.
The number of investors will increase.
There is a high probability that the price of Bitcoin will go up to 300k dollars.
There will be extensive updates on anything else.
There will still be another halving along its way. We already know what it could bring in the price of BTC. If someone doesn't believe it, they can just refer on our situation now. We aren't even on the exact halving event and the price is already pumping but how much more when we are already there?
I won't say though that the number of investors will increase because what if some countries decides to ban BTC for some reasons? That should decrease the numbers of investors instead but I wouldn't worry a lot since some countries might still replace them, so the $300k that you are saying there is still possible and apart from that I personally expect one million dollar levels for one bitcoin by the times of 2030. Let's see what time got to unfold for us...
