God no otherwise I would go crazy and lose my mind. I do check gainers and losers list on coinmarketcap to make sure my coins aren't mooning or dying. Aside from that I don't care terribly right now as all the fundamentals are still in place.
Personally I always watch the price, one day I watch two to three times the price of a coin I hold for a long time, I worry and I know this will not be good, but my mind just urged me to see the price. Are they increasing or not, how much of my capital has poured into the coin, so I always expect that they will rise again in the future.
