Not everything depends from the project. A lot of depends from market conditions. A lot of investors are disappointed in cryptocurrency projects. They stopped invest in them because they lost a lot of money.
Of course the investors are ready with all the possible risks, so, they dare to invest their money in an ico, and they know if investing in ICO will certainly make their money spin slowly, not the same if investing in BTC or cryptocurrency in exchanger, so in my opinion the team need to take the right steps by registering their tokens in exchange so that investors' money can be returned quickly.
