Are there any coins which are deleted as the time passes so as to decrease the supply and increase its value?
Also i would like to know about coins which have less circulation supply than btc and are less in value.
There are some coins which has burned their supply to be able to increased its value,ICOs are commonly doing this coin burning when the total token supply didnt sold out they will burn it which is a good thing for most of investors and bounty hunters because the coin value will surely increase after the burn following the law of supply and demand.
