Doge had some interesting speculative bubbles. Doge market cap is substantially larger than Bitcoin's was 5 years ago (@ the same age).
What are we to take away from this?
I am not sure but when I jumped in I considered BTC as the de facto base currency (something like gold) for altcoin speculation but something changed on the road.
After I stopped trading altcoins (the possibility for me to make some nice gains got significantly lower) I sat back a little and just waited for BTC to rise. I figured I made enough BTC, so let's not play it away. I waited for the big bang with BTC in my pocket. But my profits started to fade away due to the falling USD/BTC prices.
But a few weeks ago, I slowly transitioned into a state where I see the USD/BTC market the same way as I used to see BTC/shitcoin markets. Sometimes it's hard to let things go, but you must.
For example, I really liked the Darkcoin community but I didn't make a mistake when I sold it all. So, may be one day (not too far in the future), I will have to let all my Bitcoins go.
However, the margin trade options on Bitfinex should keep me going for some time. And this is a distinct difference. I couldn't short DRK even though it's also listed on Bitfinex. I probably would have kept ~1k DRK if I could short it (and thus extract the same amount of USD/or/BTC without selling the "asset").
