I totally disagree with something that you called as a Buyback Mechanism, I think that is total bullshit and a market price manipulation by the Dev. New investors will think that the coin worth in some value and buy them in the high price, but later on when the Dev runs out of money, and they cannot buyback their coin, the coin price will fall, and the investors lost a lot.
Why you say bullshit ? do you already learn deepest the buy back mechanism ideology ? that's not just market price manipulating. but one way to keep their project still a live. Good and Giant project just not thinking about the price today, the long term value in future as well.
Even if it really dropped the first time the coin enter the market, the price will naturally go up again and follow other cryptos movement without the Dev need to do any price manipulation thing like buyback their coin.
Oh man , Buyback Mechanism Build a trust for community and investor. and not easy as you say. and if that implemented in this bear market situation, so the trust foundation will go stronger. trust are the real value of the project.
