How long have you been hodling a particular coin while the coin has been making progress for your profit taking and yet dropping in your eyes ?
Some people don't understand the hodling technique, they are hodling a particular coin and never sell to rebuy again or to sell and buy another coin. You can sell this coin and buy that other coin that is how to turn over your money.
I didn't tell you to sell your bitcoin and not to buy again. I only say you sell the bull and buy the bear

Well i also prefer to sell when bull and buy in bear market because that is the best strategy but sometimes we become bord on waiting and i experience it before, i hold a coin for 5 years and yet i never gain a single profit because the coin drop,that is why i never hold only one coin i hold different coin to also have different opportunities, different coin with a different market cap can be more exciting and i believe that we can have advantage if we hold different coin.
The problem is because of our greed even if we have enough profit secured we speculate more until the very top and suddenly whales entered causing the price back to the dip and panic small inventors, until its too late to sell and we have to wait another months to recover, as a wise trader we need to have a target price if we are holding coins, if it reached the target then sell immediately and buy new tokens to hold.
We can at the beginning determine the target first so that when we have reached the target we can sell it,
when you don't have a target it will be different because the market will continue to move and we don't know what to do so when we can get a profit we continue to feel lacking,
and greed is what makes us lose
