Hello jimbobbill.
You have asked a million dollar question, here. I think that there are 100 people or more that have a similar question outside of SteemIt.
My best answer is to split what you can safely exchange (money you WILL NOT NEED) for at least nine months almost equally, but a bit more on bitcoin.
Ethereum is good or hopeful but bitcoin was the first to be accepted.
Also, there is a Chinese version of Ethereum called ANT or NEO that we have not witnessed much processing for or seen where ANT-NEO smart contract
system may do.
Don't trade more than you can lose or spend and still pay your bills.
Thanks for the reply. I was only looking at ANT and NEO yesterday. There are so many different cryptocurrencies now with more being created on a seemingly daily basis that it is hard to keep on top of them all. Your advice to split some money between ETH and BTC is good. I've still not bought either yet however.
