Yes, that's true the inflation earlier on was much higher (and I did mention that briefly in the post). I tried to make the point that it was a good investment if you look at my wallet today, even though the price in terms of BTC is down (meaning some might argue just holding BTC would have better). I didn't go into all the details of why it was a good investment though.

There's a lot of ways to look at investments and some have the goal of increasing their local FX and some want to increase their cryptocurrency holdings (usually denominated in BTC, but also ETH as well).

No one has a crystal ball that works well enough to know the future. :)

The spreadsheet I have tracks things in terms of BTS, ETH, and BTC because depending on the market I'm trading in, all of those count as "money" to me, and if I'm going to trade one form of money for another, I like to track over time if that was a good trade or not or if I would have been better off just staying in one currency or another currency.
