So, let's collect here the reasons why there will be ATH for BTC.
Name one (at least) reason, please.
Bitcoin is the only asset that really has a limit of 21 million. This is an important advantage that e.g. gold, silver or other precious metals do not have. This seems to me to be an important reason why we might see a new ATH again at some point. Sure, even this advantage is no guarantee for a new ATH, but currently nothing really speaks against Bitcoin reaching a new ATH at some point, in my opinion. Name one (at least) reason, please.
In my opinion, the supply cap is not enough to guarantee that bitcoin will rise in price and hit a new ATH, it is more important about its demand. I mean, even if bitcoin has a limited supply but its demand is not high, people don't value it, it can't go up in price. Supply and demand need to work together, higher demand than supply is enough to trigger higher bitcoin prices in the future. So, whether bitcoin goes up in price and hits a new ATH is entirely up to us.
