I have a few other alt currencies like ETH, LTC... Many of the alt coins are more difficult to gain access to and I haven't had time to read their white papers. EOS is another one that seems very promising.
I'm wondering though about some of these other alt coins how decentralized some of them are. It seems to be a trade off between being efficient and able to get something done and lagging behind the way bitcoin does because there's no central authority.
I just missed the dip in June when Vitalik Buterin's death rumor sent the coin down to 10 cents! You don't want to be in the situation where the death of one person can mean the end of the coin. But I hold onto ETH because of its smart contract platform.
Most of the BTC mining is done in China. Authorities could deal a major blow to BTC mining easily. https://steemit.com/eos/@iang/eos-with-dpos-is-immune-to-the-gfw-attack-because-it-is-more-decentralised

One of the main reasons BTC can't really get anything done is exactly because it has no governance model. BTC is a tragedy of the commons.
Buying ETH with fiat is just as easy as BTC and several exchanges are already adding Dash/fiat trading pairs. The P2P buying opportunities are also improving. BTC on the other hand is going nowhere except down and Wall Street.
