A profit or loss isn't realised until you sell. However, if you are holding Bitcoin for a long term gain, then you may be missing the chances to increase your holding by scalping or other trading.This is why I keep a small balance of fiat/Bitcoin in wallets with Coinbase, and I have made a few gains with these whilst the market is moving sideways.
But you know , not everyone does have time to actually check out the wallet balance and then trade also trading is not something that is a straight thing .
You do need time and effort , both.
I think holding is like gaining profit over long term but that too profit is passive. Therefore I think everyone can do that .
