Let me clarify what I meant in my last post. What I meant to say is, if you want to "grow" your Bitcoin (assuming you want to increase the number of Bitcoin you earn, spend/trade 80% of your coins and put 20% to sleep. I am sill a newbie in Bitcoin (following the charts only for a year, have not known much about trends) but what I meant to say is saving is the best way to achieve getting what you want in life.
The discussion is not about saving or not saving...
the discussion is about let or not let sleeping bitcoin.
You can exchange your bitcoin for dollars and then you let sleep the dollars.
Any way you can only see "after" what was the best who was to do.
After all is easy...the difficulty is to do before.
