These are the coins I am watcing for 2018 and that I think will do well:
- Bitcoin - store of value
- Ethereum - smart contracts
- Litecoin - easy and cheap transactions
- Ripple - for working with banks
- Cardano (Ada) - alternative to ethereum, also trying to improve cryptocurrencies
- Iota - for the interesting alternative to blockchain and focus on internet of things
- Stellar - focuses on the developing world
I am still looking for a privacy based coin (dash? Zcash? Monero?) and am also considering storage coins (Siacoin? Maidsafecoin? Storj?).
