Given the size of your investment ($1300), I'd consider going all in on Ether.
Bitcoin and Ethereum both have very good long term growth opportunity, the challenge is that Ether is way earlier in its run than Bitcoin. With Ether currently trading at ~$250 you can buy more Ether than you can bitcoin and it's the number of "shares", coins you own that will give you real leverage to gain return on investment from any price growth in the future.
It's feasible that Ether gets up to the $2000s level and beyond (just as Bitcoin has). And with a cost bases of $250 you stand to make a 10x return on investment. However it's less likely that Bitcoin would take the same 10x run over the same time period...do you think Bitcoin could hit $25000 in just 3 years?
This is a
terrible, terrible explanation of Bitcoin's relation to Ether and their respective prices. Ether's supply is more than four times higher than Bitcoin and its market cap is more than half that of Bitcoin. Therefore a price of $2000 would only be practical if Either ended up being worth about four times more in market cap than Bitcoin is now.
Also, who's to say that Ether isn't "the one" and that another cryptocurrency doesn't have everyone throwing all their money in a few years later? If we were actually judging new coins based on merit this would happen 24/7.
Not to mention that Ether's transaction fees are much higher than several other coins, that problematic bugs have been found in it and that it's not a Bitcoin competitor but a platform for decentralised blockchain applications.
Ether could go higher but the two are not in the same boat.
In the end you need to be happy with your investment, and diversification definitely plays a part.
It does indeed. With a small investment like that just Bitcoin and Ether is okay - if you were investing more I'd consider several others too.
I just wanted to add my thoughts as someone who knows a lot professionally about these sorts of things.
I honestly doubt this.
