There are many challenge that impacts negatively on cryptocurrencies.
While we lay blame on these guys; let's try and ask ourselves many questions like: Where are most of the funds raised via ICO's kept.
Cryptocurrencies were supposed to be cash backed yet; some ICO project organizers will prefer to stash most of these funds in their Fiat based bank accounts.

This is quite bad and needs to be checked.
Nevertheless; we expect a befitting and joyful news in the cryptosphere.
Crypto enthusiasts will smile again.
