Just starting out. I figure learning how coins work is at least as valuable as holding them if you think they'll be worth more in the future - so currently just buying tiny amounts to move around & grok the whole ecosystem.
- Bitcoin
- Litecoin (easy to buy with fiat and much lower transaction fees than bitcoin so less expensive to play around with)
- ETH (I'm a programmer, smart contracts seem fun)
- Bitshares (see ETH, also cheap to trade, keen on crypto stuff that actually ties to the real world)
- Steem (see Bitshares, also mainly just keen to learn more and engage with the community)
