My top three picks would be monero, civic and ethereum as all of them appear pretty strong and promising.
MONERO is the first project based upon the idea of complete privacy and security. The transactions are completely secure and untraceable. The project can show good amounts of growth in future.
CIVIC is a very unique project based upon the idea of identity verification with help of Blockchain technology. The project has alot of potential and can show tremendous growth.
ETHEREUM is one of the most popular project available in the market and is currently the most popular platform for hosting ICOs. You can expect the price of ethereum to be above 1000$ within 2-3 years.
