There were a lot of profitable bounty in the last year. In the first half of this year, we can still find some potential bounty, but since the second half of this year, I have found that the bounty in the bounty section is getting less and less. More than 90% of the bounty is disappointing, I don't see any revolutionary projects.
This is a manifestation of the decline of the market. It seems that ICO model has been difficult to finance enough money now, so these ICO-based bounty, the risk of not paying is also getting higher and higher.
It's hard to find a satisfying bounty /ico now,how long do you think the bounty can live?
So many ICO now after entered in the market frequently the price are down. Maybe this is the reason why investors are discourage to invest in any ICO. Also the other reasons are the bear bear market and scam ICO's. For the answer of how long the ICO exist no one knows, but if the situation like this continues and not change maybe ICO's will vanish and ether may become useless.
