Perhaps because many people (investors) were disappointed with ICO scam, negative perceptions of Crypto were excessive so there were many positive conditions, but it did not affect bitcoin to create bullish.
Thank you for your answer, we must have a solution to avoid any scam ICO. choosing a good investment place in each ICO is a more difficult choice than the trading world.
investors must be more careful when investing in an ICO, the important point that must be considered is the vision and mission, and project prospects in the future.
