Bitcoin is alway the first option for me, alsO Ethreum, Ripple etc. I am keeping mainly to the top currencies that have already developed products and are working to expanding it rather than on the ICOs that have solely and MVP. You can find my main 4 coins below:
Stellar Lumens
Stellar Lumens is a similar technology to Ripple, however, instead of focusing solely on the banks they have built a system to integrate merchants, banks and the general population.
Historia Network
A novel idea. To keep current happenings on the blockchain. To ensure that in the future third parties politicians and etc wouldnt twist facts based on their needs.
Monero (XMR)
Privacy enabled by default. There will always be a demand for an anonymous channel for commerce.
BitTorrent
The token that enables blockchain mass adoption
