Main tendencies and ways of development.
ICOs raised more money in the first three months of 2018 than the whole of 2017.
But... there is an accurately traceable tendency: the quantity of ICO promptly grows, and investors become more experienced and wise. Nowadays it isn't enough to make a beautiful website and promise something in the future. Now, to become a successful project and receive necessary investments it is important to:
1: show the MVP (product, prototype)
2: have big marketing budget
3: go on various events
4: have agreements with exchanges
5: show ROI to investors
6: have max. transparency
7: have legally protected product
8: work actively with the community
9: have a powerful team and advisors
10: meet investors F2F
11: have a descriptive WP (with clear financial model).
Generally there is an evolution, and investors consider all ICOs as serious business projects that by now follow all aforementioned criteria. If you want to carry out a successful ICO, you should remember all of this. If you don't have something or you are going to hide behind your computer your chances of a successful ICO are nearly equal to zero even if your idea fantastic. Now realities interest all, not imaginations. Good luck!
