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

There are many old threads on the Bitcointalk forum from 2011.
In one such thread, I read how one trader wrote: “Bitcoin hit $10. My advice to you is sell bitcoins! The price will not rise! Personally, I sold all the coins I had."
I also read a story about how one trader sold 5,000 BTC at $4 and was glad that he made a profit as a result of this transaction.
All these stories show that it is very profitable to hold bitcoin. Those who tried to trade in 2011 made a profit. However, this profit is negligible compared to the increase in the price of the asset over the next 10 years.
But it makes sense to hold only such fundamental cryptocurrencies as Bitcoin, Ethereum and Monero. Over time, their price will grow.
