In the coming years, according to Bitcoin experts, adoption will increase. He claimed that 3.7 million coins are lost, with the remaining coins being held on chains by early adopters.
There are no Bitcoin experts and If you're going to give a report, you should include the source of that report.
Firstly, there are no groups of early adopters who own the bulk of bitcoins, the distribution of holders is spread among a wide range of adopters from early to late.
Also, the number of potentially lost bitcoins are unknown, everyone can only make conjectures to the amount.
Avoiding a centralized authority controlling the system is one of the issues that Bitcoin seeks to overcome. If there is a large demand and widespread adoption, a supply shock would then occur.
A supply shock is defined by many as "an unexpected event that changes the supply of aorodict or commodity". This cannot apply to Bitcoin as the amount of bitcoins in circulation and that would ever be in existence is public and cannot change.
