Now the difficult period for the crypto-currency market is just continuing, including for ICO projects. Therefore, most likely, such a solution can be true for the current time. The bear market will pass, then investment in ICO projects can be resumed.
I have been very skeptical about ICOs for a very long time and I always believed that it was far more prudent to invest your money into bitcoins or cryptos rather than investing in an ico which may run away with your money at the long run and it always seem to happen.
