All things crypto were hot in 2017. ICOs (initial coin offerings), especially, gained tremendous popularity and became the preferred funding method for many investors and startups. More than $5 billion was poured into ICOs last year.
Startups love ICOs because they ease some of the limitations of venture capital funding, notably the intense competition. ICOs have opened up a whole new segment of investors by becoming accessible to everyone, including retail investors. But ICOs have their limitations, a primary one being that very few of them will actually succeed.
