1. Other projects do buybacks and burn Or burn to reduce supply to help with the price. Some project does burn tokens but you won't see any changes In price. Holders don't burn tokens only developers. BUT
2spice burn tokens on every sells. When holders sell tokens are burnt removing that amount from the circulation supply. Dev can buy back and burn to help price but dev can't burn tokens without buying. So holders+dev buy and burn tokens to increase the price.
2. Other projects have a million or trillions fixed supply or a minted supply from the start plus extra minting for rebasing etc. BUT 2spice is starting with 1 supply that is 1:1 1spice pair it 1busd. When people start buying tokens are minted and added to the supply and when they sell tokens get burnt removing that sold amount from the circulation supply. Percentage from buy and sell goes back to the contract. So burning + fess increase price. tokens are backed by an internal pool, All tokens that are minted have stablecoin backing. All mints are done with a stable token backing there is no free mint which other early projects don't have.
3. Other project contract don't store LQ, LQ are locked somewhere else. Dev can mint token and drain Lq. Because LQ is locked. BUT 2spice contract is a LQ dex itself that locks Lq. Only sold tokens can withdraw funds from the contract. And we can't mint without price backing.
Yeah so... it'll sounds a little bit awkward and rude but I didn't mean to... however, point number 1 is exactly what other projects offered, they tax every transaction, and certain amount of these tax goes to a buyback pool which later will burn those bought back token. IIRC, some project even offered an automatically reduced supply. For instance, you bough a token which current rate would give you 1,000 token, you'll receive only 900 instead, since the 100 automatically sent to the burn address... although I have to admit that I am not sure if this is just my imagination or some of those project do offered this exact concept. As I said, it's kinda vague, it's difficult to clearly remember the concept they offered since paying attention to each one of those projects are near impossible during that deflationary-NFT-bored-panda phase. There are hundreds of them with almost identical concept.
For point number 2, you do aware that total supply of BUSD is 18 billion, right? That's several digits higher than the millions. And for point number 3, as I don't want to assume, what is LQ?
