I don't know if there is ''smart'' holding the way to think of it but what I guess is that holding with passive income? isn't that it?
Holding bitcoin is a smart way because it has the highest volatile coin in the market, knowing that it already reached a skyrocket price last year.
I don't see probability with your speculation seeing bitcoin on $3000 range with the market now and for longing the range at $8000.

Smart holding is holding bitcoin.
