But for token burning, which the altcoins use to convince their holders and investors that scarcity is being created, they move a certain amount, which they intentionally created from the very beginning, and they know it's too much for a project yet they created such an amount. At the end, to convince people that it has been moved out of the market, they send the agreed amount to be burned sent to an address that no one has access to. This is token burning, and this same project developer can still mint tokens from no where most times and add them to the market, or sometimes they can do a contract swap and from the old token to another, which will give them the chance to create more tokens.
Buy back and burn token programs are non sense to create value of a token. It's solely marketing initiative.
Thinking about those programs like their developers are free to code and set any amount of token total supply they want for a token. No restriction on what is the maximum total supply when they code so if they want their token looks to be scarce in total supply, they can set it low. If they want to make it is not scarce, they are free to set it high.
There are two strategies: set it low at start to make hype that if investors are slowly, they will miss the train to get rich; set it massively high like Shiba Inu and many tokens, then use Buy back and burn programs to burn tokens later.
The second strategy looks odds in my view.
Yearn Finance with its total supply is only 36647 $YFI tokens is an example for a first strategy. You zoom out the chart and will see its price was about $40,000 in 2020 and $70,000 in 2021. It's a most scammiest and most successful scam token in history.
What is the benefit of buring $SHIB?Yearn finance.
