Good list, even if it is numbered.

The only thing I would add is to do the math on mining.  Straight up power cost vs. coins produced, independent of capital invested.  If you can buy coins cheaper with electricity, then mine.  If you cannot, then invest in coins.  If you're mining for short term profit, then you're in a different game than me.

I've mined off and on since 2013.  Never sold a coin.  Converted to other coins, or traded coins for miners, but money goes in and never comes out.  Coins for miners is probably one of the worst investments I ever made.  If I had bought coins with fiat and used that for miners, then it would have been a better deal. 

Hindsight is a fun game.  Especially in this market.
