Buyback is not a good business model. Look at Bgogo. It is tanking prety hard because there is no liquidity and they have made the mistake not to use Bitmax model plus Bnb model. What people want are locked up tokens like eterbase is going to do to trade negative fees. Also dividends are a good strategy.
I'm in agreement with your view in regards to the dividend model, some investors are comfortable with the periodic dividend that projects gives and are compelled to hold some tokens to ensure that they earn some passive income. Reducing the amount of token in circulation would also help to keep the value relatively stable, because of the impact of demand and supply.
Indeed dividend is quite good but look at projects like BOLD4 their dividend has not achieved any fit. Before investors can be compelled to hold, the team must show them the light at the end of the tunnel otherwise dumping is inevitable. As a matter of fact the so called dividend will further increase circulation and from there you can tell the outcome. It all boils down to how the team is able to champion the course
This is also true. Coinsuper exchange is using the dividend business model but their token also is at it's lows. I think that Bitcoin and ethereum rallying are dragging these coins to their btc/pair eth/pair.
