no, buyback is not a new way to attract investors and there are already many examples of projects that do it that way but still cannot make a big demand in the market. ways like that can be done if the product has attracted a lot of people
true, to attract investors the team must make another strategy besides buying back coins that have been traded, I have participated in several projects that do that, but the price remains the same in the market, there is no high increase even though such a system is done
The acquisition will not solve anything if the team has no future strategy. I think that instead of buying back, the group should spend that money listed at big exchanges because high liquidity exchanges will often attract a lot of new investors to the project.
Besides, it is possible to seek more partners to make the project gain more trust from people, and this will help investors feel comfortable choosing to hold in the long term.
